Custom backgrounds to fight on where you could just put any picture you wanted as the bg, or you could even allocate a whole folder to that so you could have it be random.
Have you ever heard about a game called Monster Rancher?
if not I will give a quick explanation. It is a game where you take data from cd's to make a monster that has a main type ans a sub type. think like the pokemon mixer stuff. you take the monster and train its stats to either take it to fight in tournaments or go exploring.
That was a really short explanation but it should give you enough information to answer my next question.
Do you think that Somebody could make another game like that without infringing on any copyright or intellectual property?
I love Monster Rancher back when I was younger. It always frustrated me that my monster kept dying before beating the game and have to start over again.
As for the question sure I would say it's possible to make a similar game to Monster Rancher but it wouldn't be our Monster Rancher though.
Nintendo got it and made some terrible games for the ds. they were based around the circus and you didn't even get monsters by putting games in to your ds. Or at least that is what I understand. Wikipedia probably has a better answer.
What is a game you thought was main stream but it turned out wasn't? or the opposite would be funny too.
