Just in case you guys haven't seen it yet:
The assets for sale on humble bundle (12 USD to get all the tools and assets).
There is a LOT of stuff, I will buy tonight to check the licenses, be warned that some assets of the last humble bundle had a RPG maker only license, so I can't guarantee this won't happen again.
Really good prizes, the game must be made for this contest (i. e.: you can use a former project) and you have up to august 7th to submit your game, so hurry up guys!
Good luck for anyone who will take part
