My nephew said that ETM was great on the GameCube. Haven't seen it on that platform. It absolutely sucked on PC. I thought the hacking interface was the most fun part. The rest of the game was clumsy and tiring. I entered the cheat codes early on in the game just to get to the end so I could uninstall it.
P.S. was it just my hardware, or were the game sounds too loud to bear, and the cut scene dialog too quiet to even hear?
