Enslaved is beautiful, interesting, well-acted, and highly polished. Why no recommendation? It's hardly a game at all.
I love the world, and the atmosphere they've created. I like the characters, and wanted to see where their story went. If it weren't for that, I would have quit after the first level. This game is totally on rails.
Your character, appropriately named Monkey, does a LOT of platforming. Most of it is climbing walls and jumping from perch to perch. The problem? You can't miss. You hang from one pre-determined (and helpfully glowing) spot, hold the direction of the next one, and press A. Then you get there, and repeat. There aren't even any choices of where to go; you're simply following a path. Even though you're jumping around like a monkey, it's effectively no different than walking down a hallway in FF13.
You can't even hop down from platforms in non-predetermined places. The game LITERALLY won't let you die from jumping the wrong way. Even in dramatic sections where the wall you're climbing on is crumbling away, you can rest assured that you will make it if you simply hold up and mash A. Seriously. As long as you push the button, you will never lose. If you somehow DO manage to die, it only feels like the game's fault.
And that's the biggest problem: with 90% of the game so streamlined, whenever something isn't immediately obvious the game grinds to a halt. More than once I found myself completely baffled by what to do next, simply because the game had never asked me to figure anything out before.
I beat this game back when it came out on 360, simply because I wanted to see how it ended (Answer? Very strangely.) Now that I'm REplaying it, all I want to do is fight the on-rails system in place here. I find myself constantly grumbling about how Monkey won't do what I'm telling him to, because it's not exactly what the game WANTS me to do.
It's obvious that Ninja Theory really just wanted to tell a story and make some nice cinematics, only adding the gameplay to glue those elements together. You are an actor in their movie, with lines and marks that you must follow, and that comes before actually PLAYING anything resembling a game. If those elements appeal to you, and the game's on sale, you might ultimately enjoy it.
Just don't expect to PLAY it.
P.S. As far as the port goes, it ran well on my PC, but it doesn't support 2560x1440, and if you have both a controller and a joystick, you're gonna have to unplug one before it'll work.
