That would be cool something like Bust a Groove.
I remember Lilith did have that but as a move
And something had been done in mugen
I think doing something like Capcom Arcade as a whole location would be nice.
A Sakura Arcade would be an interesting Bonus Games for SFV but stars Darkstalkers characters, Warzards, Cyberbots, Techromancer and other games from Capcom with fictional creatures instead of Street Fighters.
But it should be implemented with this
The interesting part in Capcom Arcade is that you get to have a random CPU challenger in the arcade games like SF2.
But the navigation should be implemented like this I used to enjoy this interface that you can navigate the environment of the arcade center.
