"I'd be more worried over getting an earful of Despain rather than Nintendo's attack dogs."
Lol thats the truth, hehe.
To be honest, I don't see how things like this can be illegal, but then again, are the rips from websites legal ? Anyways, I don't think they'd care about a non profitable game that like 200 people will play, it's too small to be brought to their attention, and even if it did, they'd just watch, and make sure it isn't sold or anything, I guess if noticed, something in the credits like "Big thanks to Nintendo for making the awesome pokemon games that inspired me to make this", which to be honest, is kind of fair, if they don't want people using resources from their game, they should make them export-proof, how this will be done, I have no idea, lol, but something could be done lol.
When a Pokémon game is made, for example, here on the forums, it should have in brackets (Fangame) or something so the Nintendogs don't bark at them, and try to use custom monsters or something to avoid a copyright breach.
