A fast 3D accelerator is a must for getting the most visually impressive Mech styling, but MechWarrior 3 boasts some incredible scalability as well for underpowered systems. I'm not crazy about the mouse and keyboard control scheme (popularized by first-person shooters) for MechWarrior 3 because controlling a mech requires a steady interface more than a twitchy one. So make sure you have nice programmable controller (my pick is the Xterminator), because there are plenty of commands that a player will be compounded with.
Hard-core simulation fans will feel a bit betrayed by the slightly more light-hearted style, but more casual gamers will be surprised at the dramatic Wing Commander-ish atmosphere and its ease of operation. While the game seems a bit complicated for younger gamers, I'm sure more inquisitive and robot-crazy kids won't have too much difficulty getting around MechWarrior 3, especially with its excellent training mode. Lastly, play-life has come into question because there are a limited number of missions. I personally am not bothered by it since I believe in quality and not quantity. Plus, there are instant action modes and standard multi-player features that help alleviate the brevity as well.
Die-hard fans of the Mechwarrior series will not be disappointed—I sure wasn't.
