Ugh, BF1942. I swear, if my computer had a soul, that game would have devoured it. It's enough that it nearly destroyed the rest of it.
If you've got 1942, and it works, good for you. Bastard. Enjoy Vietnam, it looks fun. If you haven't bought something of the series yet, don't. From what I've seen happen to my and my friends' computers, you've got a 50/50 chance of it either working or summoning Satan directly onto your hard disk, and while it seems a nifty game it's absolutely not worth the risk of semipermanent damage. Fantastic idea for a game, now if only they could find some coders who could write their name without making it somehow ****in' viral.
