My favorite arcade games were Galaga, Rampage and NBA Jam. Time Crisis 2 was also fun to play because you could use those plastic guns and I remember that was pretty cool as a kid. Pinball machines were also fun, but I was never any good with them. Mostly just closed my eyes and hoped for the best while watching the effects/animations events if I were lucky enough to get them.
That guy is playing Galaga! Didn't think we'd notice, but we did.
