Think it will be annoying? Think again!
First off, the system requirements are ridiculously low and the graphics are awesome. I have no idea how Valve pulled that off but hell, I'm not complaining!
Then the game play. The game play is the classic FPS style with a pretty good sense of movement and the surroundings although you might wanna stab someone when you start spinning through the portals.
The game interface is amazing and very simple which is always a good thing. You can play with a controller but I find it difficult cause of certain analog stick issues I had, I can't be sure that's what always happens as I haven't seen any complaints about it.
Story will be blurry if you haven't played the prequel so you might not understand everything at first. GlaDOS is the machine that controls that place and you kill it in the first game. Now it gets back alive and you gotta try and get away from that place. Things gets worse later... basically the story is fairly serious while the dialogue is completely hilarious and you can't not laugh when you listen to both Wheatley and GlaDOS.
It seems that the game is quite longer than the first one and that is absolutely awesome.
It's not a 10 just because I think it can get better than this in some way but Valve, you've done a good job.
