Are they any good?
I know I should try them myself but I tried Spiral Knights and got bored by the time I reached the first camp. Also playing hats fortress for so long has spoiled my expectations for customizability of characters. Only 3 designs for helmets? Really? Even a spy that most of the time is disguised as something else has more hats
The games I see that are free are:
Global agenda: Free Agent (MMO)
Champions online: free for all (MMO)
Spiral Knights (MMO)
Alliance of valliant arms (FPS)*
Forsaken world (MMO)
* This title reminds me of that site that generates random war themed video games titles ... the developers might have used it
