Piranjade: DieselStörmers by Black Forest Games.
After the unsuccessful Ravensdale kickstarter (which I backed) BFG is giving the project a new chance under a different name and this time they offer a playable
prototype.
gandalf.nho: Not backed because of the co-op focus and I prefered the original idea for Ravensdale (a RPG)
I find the project itself interesting enough, but seeing this
"As supporters of DRM-free gaming (see Giana Sisters) we will provide a DRM free version as soon as the sales success makes it viable to set up this infrastructure ourselves." I'm not sure if I'm willing to wait for a DRM-free version that might or might not come.
Singleplayer + multiplayer via LAN would have been good enough for me.
So I don't know yet if I'll back or not.
