Mine would be kinda like MAG for the PS3 and I guess a bit like WoW (never played it so I could be wrong)
I would have 3 factions, PC users, 360 users and PS3 users go at it in one massive world. It would be a first person or a third person shooter by the user's choice and a basic 3 fort deathmatch. Each console has one main base which could be upgraded with moats, walls and other shit and would be set in modern times. I would use a squad spawn technique similar to Battlefield Bad Company and there would be no vehicles in the game. To pay for fort upgrades and personal/squad upgrades one would have to steal shit from opposing forts.
Each "round" would last 23.5 hours with games ending at 8pm with the exception of weekends where it would run through Saturday night. This would allow people to come home from work/school to finish their fight and start off strong in the next round. The half hour of down time would allow players to free roam w/o weapons and come up with strategies. Highly ranked players for each platform would become commanders, officers etc and can give optional objectives to the peons who randomly pop in and out to play the game.
Just a thought
