Classic

I haven't even played it but I'm sure it's fun

Sure it's dated but Its suprisingly very well paced and a fantastic introduction to the series and the milsim genre as a whole. Yes there's options I'd like to have from later games but the missions are structured well enough and it's a more gentle introduction to a lot of ARMA concepts than I expected but still challenging if you arent used to fighting at longer ranges. Plus you can still get your combined arms kicks in. Story is pretty decent too and the soundtrack is very nice.

Works like a charm on Linux Mint
