Im getting crazy in starting threads about game recomendations, but im also crazy in buying GOGs atm so i need some advice! Now the turn has come for the simulations, im m,ost into flying sims as I just got free space and loved it but there a lot else on GOG ranging from WW1 planes to footsoldiers in ARMA. SO what do u think! WHich games are must owns!

ArmA Cold War Assault and ArmA Gold are among the best simulator here. But make sure you can tolerate several minor bugs in these 2 games.

Flying sim? Il-2 Sturmovik is one of the best we have here. Or if you don't mind the graphics, Red Baron pack.

Edit: Or if you want a less mainstream simulator, there's also a submarine (u-boat) simulator.
