As for me? I would love to see a game that is a mix of COD4 and World of Warcraft. Game like Tom Clancy's End War, but rather then be the commander, your solider. It would basically be set up like this:

You start of as a renegade solider in a Human ending war. You get to chose your side, The America's Faction, European Resistance, and the Free World Rebelion. You start off as a one man army, free to roam. You go around, fighting your enemies, using gorilla tactics, you could be very sucessful against small groups. You can recruit friends and people to your batalion. You'll be able to, much like WoW, level up your fighter, with perks weapons, clothing, vehicles and so forth. You'd be able to run around fighting the enemy in realistic battles, if you win, you can recruit or capture POW's. and vice versa.THis would pretty much go on forever, as you grow your army bigger and badder. Its a bit of a rough idea, and a huge one at that, it would have to be done on a large scale, i dunno if it could work, but it would be a kick *** game if possible!

so thats my idea, whats yours?
