My Fav games of all time have to be (in order of greatness)
1. Freelancer (replayability is excellent with all the mods and Storyline is extreamly enticing and suprisingly realistic)
2. Age Of Empires 2: conquerors (multiplayer is extreamly good when playing select rules and the game is *almost* totally balanced (Persian war elephants !!!!!! which i never use) I about 60 seige onagers and have an economy too maintain that nuber with about 10 seige workshops fully lined up)
3. The original counter-strike (which is very moddable even by a noob like me and is very fun to kill ppl lwith a Kreig or wolverine claws)
4. Stronghold and Sronghold Crusader (great isometric game which really test your ability as a strategic player and a manager of economy at the same time)
