Well, I'll concentrate on listing those "unmentioned" ones...
-Metal Slug series (SNK)
The gameplay is nice, graphics (especially animation) is unbelieveably good and the end of level bosses... They're simply so much over the top :-)
-Garou - Mark of the Wolves (SNK)
The best fighter game ever (What can you expect from SNK anyway?)
My personal record is 506500 points (Completed with one credit)
-Magical Drop 3
A game bit like Puzzle Bobble with 2 players, of course...
-Thunderblade
Still the ONLY arcade game, I've ever completed (NOT under emulation)
-Gyruss
Always liked that game on C64. And then when I finally found the arcade version, it was out-of-order! :-)
-Nemesis/Gradius series
Those games much defined how side scrolling shooters would be for the next decade...
-Up'n'Down
Played it a lot on C64 ages ago, later found out it was originally arcade game. Liked the red car on C64 more, though...
