I'm getting this game! I adore Street Fighter EX Plus Alpha to death back in the day! EX Plus Alpha was "almost" perfect (missing the arcade soundtrack and Plus backgrounds). EX 2 was okay, but it wasn't worth it. Excels was just an attempt to compete with Alpha series custom combos, music wasn't that memorable, Ryu and Chun-Li sounded badly I cringed, and somehow they ignored Akuma, Allen, Blair and Sakura, though the latter returned for 3. And 3 was a bit better, music was more enjoyable than EX 2.
Honestly, it needs more work but Arika doesn't have the proper AAA budget to properly market the game. For those who's getting it, let's support it so we can get the others that didn't get into the initial roster (Pullum, Sharon, Vulcano and Area) and maybe we get the actual Fighting Layer cast in the future.
