What I, personally, always loved about the BattleTech games, MechWarrior over MechCommander, was the fact that they almost played like a simulator game. A simulator game for an amazing fastastical piece of machinery that every boy would love to own. They achieved this with the control system, making the controls seem overly complicated, like a flight-sim, yet they were actually quite simple.
OT: I would love to see more of this franchise, at least an update to bring it in line with the newer games. It'd be a refreshing change from the endless Halo/Gears/FarCry clones, and give us big kids something to be big kids about again. I think that, while maybe a controller, ala PS3 or 360, would maybe be overly simplified, it'd still be do-able, which means a cross system game which may help satisfy the marketing guys before they nix it.
Heres hoping that MickySoft bring in a team of developers that love the fanchise and will do it justice, and who are also not too scrade to tell Micky to piss off when they try and dumb it down.
I think I'm gonna dig out MW4 and my old joystick and stomp around blowing shit up. ^^
