What the title says. Games for PC, not for the consoles & no browser games.

Ignore WA/WWP, naturally that's the best xD
Mine:
1.Panzer General 2
Must be about 15 years old now, but I guess the most fun game I ever played. It started turning crap when they tried to go 3d, but this oldschool 2d is still awesome. Contrary to other 'tabletop'-wargames it's easy to learn, challenging and just fun to play. First bombard them with the artillery then send in the Tiger-tank to blow up the remains 1-by-1. Objective is to capture all the yellow-border flags on the map (city centres, strategic locations, etc.).
2.Battlefield1942Classic game of course. Was great when I first played it and it's awesome still. Vietnam is also nice, but after that it got a little complicated/overdone. The essence is captured in 1942 and more you really don't need. I always had fun capturing the hillpoint at Charkov, get into one of them mobile artillery pieces and just shoot away at the enemies trying to run across the bridge that leads to the center of the city. It was carnage.
3.Age of Empires II: Age of KingsEveryone knows this game. No need to explain
4.Trackmania UnitedPlayed this online for 2 or 3 years. The only racing game that really took the time trial mode to the next level. Lots of fun to play, but a bit of a strain on the hands. The ability to make your own levels is also what makes TM TM.
5.Worms:ReloadedDespite all the shittyness... still an awesome fun game to play.
That's it, tell me yours
