I thought SE would be releasing more expansive things on mobile ever since I first saw the preview for Chaos Rings... but that was back in what, 2009? And the majority they've done since then are ports and IAP-laden stuff like Million Arthur and *shudder* All The Bravest.
I've said this before, give me a premium-priced, complete, mobile RPG with controller functionality and I'll gladly play it. The problem is, we're not getting those since the largest profits in mobile gaming come from F2P whales and "games as a service".
Also Rhythm of Fighters isn't bad but the song selection is really lacking and doesn't even have a lot of my favorite SNK tracks (and the less said about that shitty dubstep song in the game the better).
