such a good game. loved the first portal loved the second portal.
Haven't had a shot to try this yet
Haven't played it yet, want to though.
This has been out for a while. Should I buy this? Never played the first one.
Played through single-player and loved every minute of it! Haven't tried multiplayer yet. They need to make more sequels to this game if you ask me! +follow
I would say the biggest improvment over the original was the addition of co-op. Genius idea!
