At the moment i play mostly Dominions 2 .
I played a long time lots of Diablo 2 and Counterstrike but after about a year i got bored by them .
Diablo 2 mainly because the cheating started to suck too much and CS because i couldn't see Dust , Aztec , Dust 2 etc. anymore
I enjoy Steel Panthers WaW still a lot and play it occasionally again even now after 2 years , almost the same with Steel Panthers MBT .
The Paradox Games Eu2 , Victoria and HoI i still play too they are just great
Finally i bought now some cheap not really old games which i enjoy too :
Civ 3 with Conquests
Disciples 2
Etherlords
And some oldies which are now available for free like Great battles of Alexander or Vantage Master
