Battletech

Buy this game is you want some really good and challenging isometric mecha action. The really unequal difficulty level of the game (The first level is a walk in the park and the second is hell on earth as you have to run the other end of the level dodging enemy to destroy a missile base in time) combined with the fact that some objectives are quite tough to accomplish on the first try without tactic make for either a really fun or an incredibly frustrating game (depending on the type of gamer you are) The controls are really smooth and allow you to control the rotating turrets of the mech as you move around but the fun is best attained while playing with 2 players (one controls the legs making the Mecha move around and one control the turrets).
