Definitely Attack from Mars when I first saw it in 1996. I was 14/15, and I absolutely loved it. It was in the arcade of a laser tag place called QZar. There was AFM and TOM. I tried TOM and it seemed "meh" to me. AFM though.....seeing that saucer light up, hearing all the cool call outs, the music when MB started up, hearing the martian bellow "JAAAAAAACCCKKKPAAAUUUTTT!!!" with the guns going off or the missiles whizzing by on the DMD. Man, I missed entire laser tag games cause I was playing it so much.
Took me another 20 years to finally buy one, but I did just that in March 2016 at 34/35. Done two PF swaps on it since, and I came to realize I enjoy working on and getting them working again over playing. Don't get me wrong, I can hold my own, but bringing them back to life brings me a joy I simply cannot explain.
