Namco USED to be good at single player stuff.
Mission Battle, Weapon Master, Chronicles of the Sword (if you like that), Tekken Force, Devil Within, Dojo (for the PSP version of T:DR).
It's just as of late they've really crapped out on the good single player stuff. Thankfully, I've also become a more serious player in recent years so this isn't AS important (though I've also made an effort to really explore the entirety of a fighting game's offering, just so I stay grounded and not too wrapped up in only the mechanics).
Tekken Force, Devil Within and Dojo were all terrible
Single player in fighting games will always be a diversion at most.
