I just got bored today and i decided to install the old Counter Strike game from Valve using Wine and it worked out-of-the-box. Amazing. In the past, CS was considered one of the best FPS game in their era and few years later, Valve has released the sequel of this famous game.
Wine has been maturing lately and every two weeks, they released a snapshot which is getting better and better. Even though they are considered developer snapshot, they are quite stable for daily use. I have been following their work and so far, it has been a good cycle.
