Did you play either of the Mech Commander games? Both are nice isometric real time strategy type games and are really fun. There is also Mechwarrior Mercenaries that is now for free from the folks at Mektek. They've included a number of mechs that weren't in the original. Also included are the mechs from the two addon packs that were released. There is also a multi player part of the game that I haven't tried yet, but looks like it'd be a laugh. And at some point in the future, there will be a brand new Mechwarrior game that will be released. So far, there's just been a teaser vid, but it looks awesome.
