honestly, i think people overstate that problem. If you are small/indie, there's really no option to avoid competition anymore .
PSN, XBL, Android, IOS, Steam, even the Vita, all of them are getting flooded with games.
There's like, the 3ds but that's only really attractive if you are a japanese dev.
The big guys just do marketing. If it becomes a problem, it'll be a problem everywhere. Meanwhile everyone tries to spread everywhere.
Which is why stuff like the games in here start to come that never would have previously.
