[QUOTE=Bakercompany;321026]I’m only a little saddened about Rage being primarily a single player experience. I’m glad they’re throwing in a coop and MP, but i’m a MP junkie. I wanted a full blown MP focus with SP. I’m greedy like that.
Rage will still be awesome though I have no doubt.[/QUOTE]
It’s up to the modders,the guys who know how to make awesome MP mods and all that stuff.
Look at SC2.It also came with an editor and till now there are countless extremely funny multiplayer modes.

I’am pretty confident we will have some nice MP mods when modders get their hands on the SDK with Rage.
