So as I see most of the programmers are searching for an original idea for a game. In my point of view the most important is not to be original just being different from other’s product. Like Apple: iPad=TabletPc; iPod=PDA; iPhone=PDA+telephone function(Mitac,HTC made before Apple), nothing new but while PDA and TabletPC were unsuccessfull then Apple made a big hits with these products.
My advice is to make a Half-life “clone” game (on Mars), make humanoid enemies (with some non human creature). Everybody liked Half-life… It’s not original? Heroes of Might and Magic is a King’s Bounty clone so what are we talking about?
So think about what FPS games do you like and why (what kind of enemies do you like)!
Basicly , ill have to disagree with you , we dotn need any more generic shooters or generic action games imo , try to find a plot or a theme that is different from the mainstream (serious action games) and i bet it will be awesome.
The saboteur was pretty original and i loved it
