The only shooter game that comes to mind that would remain a hit is making a game like Team Fortress. The humor is mandatory.
Multiplayer has my vote as well.
yes thats true, a comedy style would also excuse most graphical flaws / glitches, doesnt have to be ton but somewhat comedic, 8 players would also do nicely and could use standard expected shooter weapons which wouldnt be hard to code, the movement could be done client side since it isnt that much of a major title.. i planned to do a game like this anyways after my current project.. so if its not done here.. i'll do it with Anet and my own team
