There are so many good factions, you can even add Morlocks, Hellfire Club, and then Shiar and space craziness (maybe just hint at that stuff to keep it mildly grounded). Have the overarching bad guy be Sentinels and mutant registration.I somewhat agree with you here. I think that black AND green gives Xbox a premium look. Give me something like Pelochoman designs and it will be glorious.
Oh yes! YES!
A game where you create your character, a new discovered mutant. You can choose your powers and appearance, and there's factions who you could choose to align: Xavier X Man, Magneto Brotherhood, Thieves Guild, Government Sentinels, Apocalypse Worshipers and others.
Ohh it would be a dream game...
Hey Microsoft, Wake_Lestat and I are crushing game design here. Give us money.
Here's another great idea I have - an Obsidian (I'll accept InXile for this one though) made Gears RPG. New character, choose background as a COG, a Stranded or even UIR soldier. Explore some standard but rad Gears locations like destroyed cities, massive science facilities, military bases, catacombs etc. Kill Locust.
