Played both many times. Couldn't wait to get another game on GB. Also missed it immensely when I left. TH gameplay did not excite me. A very slow methodical game. Have no idea what the right flipper is actually for. Needed a ramp for it to shoot at.
While TH is a great game for the non player to watch... It leaves the player completely unfulfilled. I actually the joyed TBL more than TH but GB beat them all badly.
