there are enough laser blaster rocket jumping spaceman / alien style games such as Halo, Unreal Tornament, Quake...
yet we haven't got one game of post apocalyptic style gang warfare. Rage has all the right ingredients for what could have been successful on-line multiplayer first person shooter. It doesn't have the silly rocket / anti-grav jumping around firing off untold rounds from a laser blaster as it has the more realistic element of a wargame like COD.
It has unique weapons.
the unique and fantastic designed gangs would be the teams
on solo you could uniquely design your player
It could have vehicles in like in Battlefield.
Plus it has the side option of having racing gaming for those that want a break from running around shooting.
It could also have a side game featuring motorcycles that is the inequivalent to a remake of the classic old game Road Rash
