Not sure how many games you want to add, but Id recommend starting of with a dozen or so of the big successful game. Stuff like:
StreetFighter 2 (plus a few of the sequels, maybe Turbo, and Super SF2TX, not out of personal preference, but rather 'cos it spaces them out evenly in regards to their releases).
Motal Kombat (personally Id say 1,2,3 as in my op. the later releases felt like they were just milking it)
1942 (or one of the series)
GUess I'll keep it at that for now. Even when trying to keep it minimal I feel I could go on forever
