You know, even though people say pac-man for the 2600 helped kill video games back in the 1980's, I personally enjoyed playing the game back then and even now in 2009 I still enjoy it once in a while because there's nothing like hearing "dunt dunt dunt" as you go around eating dots
As for games that rise above the rest for me, just to name a few I'd have to say Kaboom, Tapper, Keystone Kapers and H.E.R.O.
well, when your looking in to a somewhat decent arcade port, otherwise, its OK, but its still not that good.
