DMC.
Metal Gear was always way too boring and up it's own ass for my tastes.
lol What? It's cool that you prefer DMC -- so I'm not trying to change your mind -- but how is MG up its own ass? It's epic in scope, for sure, kind of indulgent but it clearly doesn't take itself completely serious.
But yeah, Metal Gear for sure. My favourite series ever, used to watch my bro play Metal Gear, but I didn't really start playing it myself until Metal Gear Solid, when I was old enough to know what was really going on.
It has the best video game character ever, an engaging story with something to say, humour, great gameplay (though MGS is a little dated now, unfortunately, but it still has the second best plot out of them and some awesome scenes), emotion, and it's one of -- if not the best -- case for video games being art, which is funny cuz Kojima doesn't believe games are art. MGS4 is a tour de force, even if there are a lot of cut scenes.
But DMC is a pretty tasty apple, as well.
