Also, quite many classics (which opens the question - what is to be counted as "a classic"?), but they are spread all over the place. I see:
(Bad Dudes vs.) Dragon Ninja
Green Berett (not sure though, it's the running guy in front of Shinobi)
Ghosts 'n Goblins (alternatively - Ghouls 'N Ghosts)
There, most of these are true classics from arcades / 8/16-bit computers from late 80s and few from early 90s if I'm not mistaken. I've managed to spot them after watching the picture for 15 minutes. There are probably more of them there. But I've got better things to do than to prove to myself I'm an old-school gaming geek!
