Finally got a chance to ride both with new tracks. Space is at best very interesting as it totally changes the feel of the ride (honestly...it seems to have slowed ride down.) The flashing lights and all are cool...but u really do see too much of the inside of mountain. I like The song...just not sure what it brings to ride. Effects are ok. I prefer SPACE version of ride. Screamins music change.... it seemed pointless.... honesly i couldnt telll the difference as i was having too much fun on he ride.....and since the sights don't change...again... it was different... i prefer original.
