Ditto what SteveO said on the Missile Command buttons, that was weird. However, from playing it I did realize that mine actually DOES need a new roller kit compared to how nice that trackball moved, so that's why i like to play and compare on other games I already own.
Gorf- all the guys on the monitor were just a bit fuzzy and out of focus, not as sharp and crisp as they could be. Apparently can tweak this in monitor adjustments/ focus knob? Otherwise played very nice
Big Guns- the ball got stuck on TOP of the upper left drop target bank when it was down, I believe you can raise the target bank it to make the target tops perfectly flush/ level with the pf so this won't happen. I was able to just shake it and get the ball loose, but I'm sure you;'d want to adjust properly
Black Hole- for my tastes I'd jack up the rear leg levellers a bit to make it go faster on the upper pf, that's what I'm used to on mine. The lower pf shouldn't suffer much as a result, but i realize it's a balancing act with that game, if you angle it so one pf is fast, the other goes the other way. IMO I'd rather have the upper faster though on this one, as the flippers and pops were plenty powerful once the ball finally got to them. Beautiful game, I still enjoyed playing it very much!
