Well since it is your laptop you can do as you want, but i do not recomend installing too many really big games because (on my laptop atleast) it seemed to slow it down, but i had Unreal Tournament 2004, Diablo II LOD, Warcraft III and Frozen Throne, and Baldur's Gate I and II with the Expansions both I&II, along with some other games that were not as big but i ended up taking up about half of my hard drive and it seemed to slow down my laptop. It sped up once again after i deleted some of the games/videos that i had on there. I now have only 2 big games , over 1 gig, installed at a time and it seems to have helped.
