While everything else was rather silly yet a similar humble suggestion like most of us, this part is a no-no. You don't have to make a M game out of SC to make it good.
Sex features.
Sexual features are fine. People online however will always make sick CAS characters(think penis on rainbow customs) that make me hesitate playing online around my younger audiences. While it's funny for me for the first few times, it becomes pet peeves. Another example is I'll see some lady who barely has anything on be aroused at first glance, take a closer look and find her wearing special equipment in a inappropiate matter(think undergarments that make her look nude. While I am male and enjoy it at first, I shook my head in disgust. Much rather see a simple Pyrrha in a Maid outfit than that. If this made series to M ratings, I just think it's be stupid. There's a lot of peeps out there who always make the same sex jokes or something worse. Despite that, I have to put up with it *sigh*
Epicness.
The game series atm lacks epicness, and it's not because of graphics. It's just meh. Every SC Soul Blade-Soul Calibur 3 imho was epic on how it felt.
Let me show you an old but epic vid from Soul Blade.
If you were to compare this vid to derpy but nice graphic SCIV and SCV openings, it had more epic feel. Music choices were better back then. While SCV did improve it's soundtrack, it's still not as mighty as the older installments except SCIV's OST. The openings imho got more meh. Soul Blade was so new and true. Soul Calibur one was followed up nicely. Soul Calibur 2 was pretty decent(removing nostalgia goggles for this one). Soul Calibur 3 did a great job introducing characters like Zas, Tira, and especially Setsuka which renewed and kept my interest.
While Soul Calibur 4 introduced Amy, Algol, and the lovely Hilde, it felt so meh. The opening didn't even seem exciting. Everything about it from my casual point of view was kinda just meh. Characters like my lovely Seong Mi-na look less attractive compared to the Soul Calibur 3 versions of themselves. That's when everyone imho looked their very best. The only casual thing that attracted me before SC4 came out, was Star Wars, but my hype for them died down after playing them. I cared about Yoshimitsu, Seong Mi-na, and the other cast more. Hardcore wise, SCIV was pretty good except when you go online. Not gonna elaborate on it much, but the net code was bad thus a silly lag code was made to weed out good players from the bad.
Violence.
The game is fine. Make it show blood and gore and I will hesitate to play. Would you want to watch as Nightmare plunges his sword in Siegfried and watch blood, guts, and other stuff come out? This will attract MK peeps but imho I'm a SC purist. Keep it Teen like Tekken.
My humble ramble of what Soul Calibur series needs?
What this series needs is to recapture the best parts of each Soul Calibur. Look at Soul Calibur 2-3 for instance. Introduced many modes that we can call "playground for the imagination". If they put more time to put these in, SCV could of had a better score.
Gameplay wise.
SCV did a great job on including the gauge, JG, quick step, to make things exciting. However, if you were to dig deeper and find the flaws of them, you'd be quite disappointed. From my hardcore point of view, the game is too simplified. I understand noobs want something easy to pick up, but some brave edge attacks like Yoshi's 6B BE feels like a noob version of his iMCF. It's okay from my point of view, but not that useful except if it's used in a combo and/or wall combo. But the thing is, the movelists for everyone feels "simplified".
My main Yoshimitsu for instance. Tons of fun in SCIV and required lots of knowledge on understanding his whole moveset to defeat my opponents. SCV it's like he became less complex compared to the SCIV one. He still functions the same, but SCV is too simplified. I took way more breaks on SCV compared to SCIV because it gets frustrating not being able to do certain old moves, but this game was rushed. What can I do?
Personally I feel once the game has all it's secrets out, everyone won't always main the same characters like Voldo. All know is I'm gonna see tons of Alexandras for instance. Sure we'll see someone awesome and different like a Tira winning EVO, but only because certain peeps don't do their HW on their opponent.
This brings me to my next point that would make more happier than casual wishing for more CAS stuff: FIX THE WHIFFING, THE HITBOX ISSUES, AND ANY OTHER HARDCORE PROBLEMS I FORGOT TO MENTION!!!!
Sure there will always be low tiers and high tiers, but I feel like poor ZWEI will never get anything more than beating a person blind to his set-ups. Or poor Siegfried with his whiffing issues. Yes, I want this game fixed and balanced.
Characters. Where everyone feels empty without the ones dear to them.
Well, I miss Zas. Grim reaping black dude that will be missed. I mean come on, he can reincarnate for pete's sake!
I miss Talim. An older and more mature Talim would of made my day, but I guess we won't see her...
I miss Taki, but her style returns as Natsu.....
I miss Setsuka, but her time is up.....
I miss Hwang and/or Yun, they represent Korea. Now PS cuts them. Pocky Yoshi sad.
I definitely miss Seong Mi-na. But I'm cool with a replacement that makes me think of her. She doesn't have to be korean, but a style like her with attractive lady(and similar personality) will do it for me.
What we got?
Natsu. Yeah I like her and all, but I can't deny that's Naruto gender bend.
ZWEI. I like his Wolf summon stuff and all, but his design makes me think J-pop/K-pop hottie star+Twilight=What is this?
Viola. A characters that's done right on design and gameplay imho.
Pyrrha. Sophitia except more crybaby, meek, and attractive than Sophitia.
Leixia. A Xiaoyu cute desu version of Xianghua. Eventually she'll grow up like her mother.
Patroklos. Happy to have a male style S&S. Though his attitude sucks, he's cheesy funny.
Elysium. Hello Sophitia reskin, I see PS favored you. Nice CE.
Alpha Pat. Hello A Pat. I see PS favored you too. Nice Setsuka style for Pat reskin.
Pyrrha Omega. Hello Pyrrha Omega, I see PS favored you three. Nice Sophitia Style 2.0 reskin for Pyrrha.
Aeon was kinda cool imho. Something nice.
Edgemaster. The only mimic that should be the only one.
Instead for certain characters. Because I'm still not over it.
Edgemaster could of been the only mimic and I would be cool with that, but if they favored Kilik, they could of made it to where Kilik is the new edgemaster and the only mimic. Or make it to where Kilik wields something new.
Elysium could of been a different character altogether. The only thing different is the CE.
Alpha Pat. This one I will suggest a new female. With Taki and Setsuka gone they could recycle and make a new oriental beauty.
Think of it as Yoshi. He has a Katana and a Wakazashi.
The new female could wield a lai sword and a kodachi would make for something new. Better than say Kunimitsu(No disrespect for this cool character).
Personality? A mix of both. Cold and serious ninja when it's mission time like Taki, but retains kindness like Setsuka.
Looks? A real oriental face with a nice slender and slightly toned body. No exaggerated boobs and asses though. Just a nice size.
Omega may be different than Pyrrha, but aesthetically a female roman gladiator would at least not make me rage as much as Omega.
Add Bangoo in. Why is Amy allowed but not Bangoo?!
In general, I understand it's hard for PS to make something innovative, but they can if they had more time. I wouldn't mind waiting 3 years if they had to do it. I'm a loyal SC fan.
Story.
Well, if they went with simple old school style(beat arcade with them, see destined battles, see ending) I'd be cool with that. It doesn't have be like SCIII story telling or so.
I think I've rambled just as much as you emperor, but I made it to where it doesn't come off as a jerk. Sure your intent was not to troll, but with the way you respond to peeps congratulations for making me respond to you a bit more gracious yet tactful than I had to. Anyways, welcome again.
