So basically I thought this might be a funny topic for some laughs (or 'lulz' in the internet vernacular), basically just come up with crazy, completely non-sensical and plain stupid video game pitches, some might sound surprisingly fun!
Skeleton-XYou play as the recently deceases Steve Kellington, a mild-mannered man who meets his untimely death after getting mugged and killed by a street gang. As it turns out, the afterlife is no walk in the park, as he is informed that to gain passage to paradise, you need to engage in a series of "death"matches (ironic, since all combatants are already dead) with other souls, the losing team must spend more time in purgatory while they wait the next challenge. All the participants are skeletons.
In a surprise twist, Kellington's killers had all died moments after him, as they spent the money they mugged from him on a tainted dose of drugs. In an even MORE surprising twist, Kellington is put on their team in the battle for entry to paradise.
Deciding this is his chance for revenge, the object is to enter these Team Deathmatches/Capture the Flag/King of the Hill etc fights and cause your team to LOSE. This also extends to the multiplayer modes, the object is always to LOSE, not win. Don't forget that both teams will be trying to lose, which should lead to some interesting tactics. (Will you rush to team-kill as often as possible, and get as few points as you can? Will you occasionally kill the opposition, even though that will raise your point-score, it also stops them from getting team kills!).
Further complicating matters is the supernatural weapons you can use. While almost every gun you have functions like a regular earth-weapon in every way, Shotguns (and only shotguns) are the exception, as they can shoot through buildings (but no other object, eg Cars or Picket Fences etc cannot be shot through).
Basically the ultimate goal of the game is to team-kill your allies with shotguns that shoot through buildings.
The game will also feature a 'One liner' button similar to "Evil Dead: A fistful of Boomstick".
