Easily Brawl, if you've never played MGS before there's no way you should pick up MGS4. If you somehow get the opportunity to play MGS2 and 3, as well as Twin Snakes, then I might suggest picking MGS4 up after that (even though I'm personally not a fan of MGS4, despite loving the series prior to it), but as it stands now, Brawl.
