ima probably enter a game i was planning on releasing as freeware anyway. its held by some of the guys behind the 2bee competitions so i think its pretty legit.
theres a lot of lawyeristic stuff in the rules, but i mean i read it all and it seems you retain all rights except to distribute or something like that when you win the 100,000k, the prize can be revoked if you break rules, not fair-play etc. but even so my game was supposed to be freeware so anything fishy doesn't even matter to me, just the publicity of winning would be nice, and the prize is a great addition too
