Well, kinda free, anyway. Sony is offering its cheap-and-ok take on Warioware for free to everyone with a Vita.
This was announced on the PlayStation Blog, though at time of press the shop hadn't been updated in Australia to include this. The free comes with a catch, though. If you really enjoy the game, there's a DLC pack coming with 15 more minigames to get into. That bit will cost you money.
So really this is a big demo. Not that we're complaining!
