I see everyone Mentioning Homeworld, yeh, that ending made me cry too. The whole music in it made me feel all lonely and sad. I even remember my next door neighbor hearing me scream "Don't harm my people!!" and related sayings during the game. Oddly she thought I was watching Dune....*eh?*
Maan, I just Reinstalled System Shock 2 because I wanted to play it again, now I wanna reinstall Homeworld!!
