Yes, because SD has just as much money to throw at it as Valve does. Feel free to post a list of "a lot of games" that were updated, though.
No need for sarcasm. Are you a developer? I am (not games though) and it is a design desicion how you program that defines how much effort it is later on to support 64 bit.
Some games (List from 2006!!):
I don't get why some of you try to defend design decisions of IC (and we all love IC) that were flat out wrong in the first place. Yes, it was sufficient for vanilla, even for entrenchment, but in Diplomacy you saw that it was no longer feasible. They implemented a new load-on-demand system now to keep mem usage down, but this will prohibit you still from adding very high res textures or many more models/effects/sounds... as you will get to the limit again sooner than you think. That might not be a concern for most of you users, but for us modders it is of utmost concern. We do want to create additional value for this game, but we need headroom. And I'm afraid that Rebellion is gonna ask for headroom itself, so there is less space left for us.
