MechWarrior 3

The Good
Terrific graphics, and good control. The missions, while not astounding, were varied and fun. Multiplayer is good, but a lot of that comes from the fact that you're able to play in FASA's universe rather than any outstanding move by the developers. The environment is great, and you can interact (blow up) many of the things in it. Weather and terrain really make a difference. Finally, it captures the feel of the board game better than its predecessors.

The Bad
Fairly short. 20 missions aren't really enough, and while they are fairly varied for this type of action game, they're rather dry compared to missions from MechWarrior 2. The enemy AI can be somewhat braindead at times. The initial release was somewhat buggy, and had a serious multiplayer issue -- you could shoot off one of someone's legs and they'd die immediately.

The Bottom Line
While not as much sheer fun as MechWarrior 2: Mercenaries (for me, at least), it captures the feel of the board game quite well. If you don't care about the differences between an autocannon/20 and a medium pulse laser, though, MechWarrior 2 is probably a better bet if you haven't played it already.
