Personally. Rondo>Vampire Killer> IV. Sure the graphics aren't the best, but it does cool stuff
with the MD's great parallax abilities. It's the fastest of the three, and in RGB looks fantastic,
I like all the boss fights and is probably the best of them in pure action.
IV has great atmosphere, but the gameplay is absolutely terrible, stupidly easy. And the lamest,
crappiest boss fights in the entire series. Just stand there and whip, bosses die before you do.
