I liked, and completed, Tower Assault. The problem was that by playing Tower Assault first, going and playing the earlier games where you couldn't backup and shoot was annoying as hell. The CD32 version of Tower Assault has issues though. I can't remember them off the top of my head but accessing the map caused the game to hang and there was a glitch with one of the weapons whereby you paid for an upgrade but it stayed at the standard power level.
