And a lack of polish with all the bugs and glitches.
Lapsed SC player just getting back into the game with VI here, sorry for inserting myself into the convo but this is one of my buttons. XD
SCIII is also my favorite game in the series, and I think it's a bit unfair to accuse it of lacking polish. It had
one bug - granted, that bug (along with the resulting version differences) killed any chance of a competitive console scene, but it's more sad than funny that all it took was VC to ruin the reputation of what was (IMHO) otherwise head-and-shoulders the best game in the franchise (roster, mechanics - especially GI, stages, score, aesthetic, etc.)
[edit: at this point I'm alerted that Dante has posted my exact feelings while I've left the editor open. :P]
I agree with what he or she said, and I think the slow, sad deflation of the SCIII tournament scene only encouraged Namco to lean into the "reinvention" aspect of SCIV. Oddly, I feel SCIII:AE came
too soon, if anything. Six months later and with a little extra content it could have maybe merited a console re-release, but basically walling off the fixed version of the game half a year into the title's lifespan only contributed to the community's dissolution. [Rewriting this section, felt awkward.] My feeling is that Namco got the wrong idea with SC3's strong sales and short life, and leaned into the character creation but away from the core gameplay, assuming it needed more flash. To make the game look less "simple" and more cinematic they implemented supers and longer canned combo strings, but the armor-break system contributed to the game state being a lot more difficult to read (with stupidly granular damage boosts to armor-broken areas, and surprise armor-breaks baking in a swingy comeback factor. Also: half-hidden information, like which of Yoshimitsu's Iron Fist moves might come out, or whether Hilde was holding doom combo charge or not.) I disagree with nearly all the changes from 3>4, and feel the bombastically supernatural / less historical tone was a poor choice as well.
I played nearly as much SCIV as I did SCIII, both because of the online matches and because I found a new local scene, but my time with the game was somehow joyless. I played SCV exactly once (GI takes meter? GTFO.) In my time away I've become a much better fighting game player in general, spent quite a bit of time going deep in other games, and considered Soulcalibur a "closed book" with SCIII:AE (still waiting on a home release.) At first I didn't give SC6 a chance, but the last three weeks have been a
revelation, and so far Soulcalibur VI has felt like a return to form. I miss the high/low, counter/parry GI game (not a huge fan of reversal edges, I hope 2.0 speeds them up significantly,) and I'm hoping SCVI receives continued funding from Namco to increase the in-game content (characters are on their way but we need more stages!) but this feels like a Soul Calibur game made by devs who actually love the elements that set the franchise apart. If things go well, we may be in the second-best timeline...
