yeah, good tutorials for one. And they take WAAAAY to long to play. you can't sit for just five minutes, or you don't actually end up doing anything.
CNC Red Alert 2 was THE best cnc game, in my opinion. It's the most balanced game of them all, so it can be rather relaxed.
Every one needs to play the PC version of Oblivion or one of the other Elder Scrolls games (why I have an Oblivion Gate as my Profile icon), just because they have SO MANY THINGS TO DO! One of the great features of the Elder Scrolls games is that if you spend time looking around you find really choice things. That's why I don't like CF and other Fast-paced games. You can't explore around (granted there's not much TO explore), and the election of what to do is very limited.
