Nothing?
Disappointed.
Well, yeah, Homeworld. The first one specifically. Homeworld is also notably the only game to pull off "Oh look, this planet is going to blow up" effectivley by using the unique twist of actually just blowing up the planet at the start of the game and getting it over with. I can't explain why it works with words, it just *does*.
Quick edit: Actually, will give it a try. Instead of the usual "Hate these guys because they want to blow up the planet and kill all these people and you need to stop them before they do!!11!1!" It's more of a case of "Hate these guys because they did kill all these people and theres nothing left for you but revenge." Have I done it justice? Certainly not, but for those that havem't played it, hopefully it will give you a rough idea of why I liked it.
Edit2: Oh, X-COm as well. It's far too easy to get attatched to your soldiers after a few missions. Even if they have literally no personality. The game is (relativley) basic though, so it seems that I, and most others I know who liked the game, gave personalities and little stories to all the characters. They were all generic soldiers, and completely blank, but with the nature of the game it lent itself easily to the player filling in the story and personality of the soldiers and making the player actually care, or hate them accordingly.
