A bunch of games really and emulation.
I could Lanplay with Soldier of Fortune 2, Battlefield, Unreal Tournament with lots of players and it was great. My PS1 died and I had to turn it upside down and I got another one and had to do the same, my PC was the only way I could play the rest of my games, and the same with my PS2 allowed me to progress in SoTC.
But really, in terms of games later on I'd say Warlords BattleCry series, BattleRealms, and Dungeon Siege 2. Oh yeah, and the tons of f2p MMOs(I currently play Vindictus alot and previously Granado Espada) and arcade games I can play for free which I get from various sites(no pirating).
