^^I don't think it's a particularly good game, but it's fun in a goofy old-school sort of way. It isn't really a port though, it's a whole new game on its own. I like the second Sonic game for Master System/Game Gear a lot more, the gameplay is tighter and the areas more unique. And they don't start you off in a "Green Hills"-esque zone for once.
I was having a pretty good time going through FFXIII until I picked up Skyrim a few months ago...comparing them is apples and oranges really, but Skyrim is just astonishingly more fun, deep, and epic. There's certainly more of a thrill to pickpocketing a bunch of gold off of someone than an umpteenth Paradigm Shift.
