So basically the decisions involved in the creation and release of SFxT killed Capcom All Stars and new Darkstalkers? Awesome :/
Trying to game the system with when to release fighting games I don't think is really as helpful as companies think ti is. Releasing SCV early, and thus undercooked, didn't help that game at all - the lack of content killed it with the casual crowd. If Capcom were concerned about the quality of the games above all else, UMvC3 should've come out in SFxT's slot and SFxT comes out that holiday season or early the next year. SFxT was clearly not fully cooked at release. Given it had Street Fighter AND Tekken in the title, as long as the game was fully cooked at launch, it wouldn't have been threatened by other titles (nor would Capcom care about cannibalizing those other games). The Pay-to-Win Gems, terrible marketing, the fact that the game looks awful and DLC practices didn't help though.
Assuming UMvC3 was given the full time to develop and released in March 2012 instead of late 2011, when would SFXTK find an appropriate timeslot for release? If you're not already aware, 2012 was PACKED with fighting games.
Just from what I remember: SCV, TTT2, VF5FS, Blazblue, Skullgirls, DoA5, and P4A. Between all these games, when would SFXTK have had the chance to release without getting itself cannibalized or cannibalizing another game in the process? That's also the reason Namco pushed SCV out way ahead of schedule in January because they didn't want the game competing with all that I listed above. Plus, I'm confident Capcom wanted this game out before TTT2's september release. Part of the Tekken fanbase was definitely interested in SFXTK purely because of the brand name and if TTT2 released prior to SFXTK, then they probably wouldn't even bother with SFXTK. There's market area Capcom's losing.
Maybe you want to label SFXTK's release as the problem or the decisions surrounding it but I'd rather not call the game trash (which some are here) because it actually has a good gameplay system going for it. Maybe not everyone can appreciate it (just like with any game actually) but there are definitely fans.
