My two cents. Piboso... Please, please, concentrate on bike sim's. Since there are plenty of car sim's and even Kart sims. There is no serious bike sim at all. You have the market cornered! 
P.S. Please add Track IR support.

I canīt say more...
The bike sim (and i mean SIM not the Graphic junkies/Arcade) market is empty since years (decades :-) )!
Milestone is every year a big disapointment in terms of phsyics and realism and there is no other company (than you) who is developing a new benchmark...
A BIG thank you Piboso for:
- developing this great SIM! (and MXB as well)
- sharing your knowledge with the community
- opening GPB for modders (imho that was a big step forward)
- getting the community involved in the future development of GPB
There is still improvement for the next BETA and we all looking forward to it.
In my opinion the reason for the friendly and helpful community is the comlexity of driving the bikes.
Most younger players will leave there hands off this game because of the long learning time to drive a bike real fast in GPB.
Keep it going!!!
