I had a problem bouncing between games for a while. Usually, I practice all day on marvel then head over to friends houses to play other things and I would only practice those games there.
I spend about 1 hour a day training in marvel so I figured for me to maintain my level in all my games, I’d have to train @ least 1 hour per game. @ 1 point, I was playing mvc2 for a few hours a day, HDR and 4 for a few more hours. So @ the least, it was 3 hours worth of practice per day and more if I had the time for it.

There are probably a few more players but these are just some players off the top of my head who excel in more than one game. It helps to watch these guys play 1 game, then watch them play a different game. You get to see what strategies are transferring over and why.
