mech 4 should have stuck with the mech 3 interface, the controls for mech 3 were bad ass, hands down. mouse controlled tracking arms, sweet stuff. i also didn't like how 4 limited you to the customization of your mechs weapons. should again have retained the earlier series setups, and made it so the weapons showed up differently on the mech depending on how you configured it. but, i'll say this. mech 4 mercs was fun as hell, even if mech 4 overall was dissapointing in how they set it all up.
