Portal 2 was another great game that came after the very popular Portal 1. Unlike the first one, Portal 2 did not focus as much on the puzzles but they focused more on the storylines. Storylines isn't a bad thing but when they focus that much on it, it can get annoying. The storylines was great, but the puzzles were very "lacking". The puzzles were basically hidden in the new multiplayer option. Where you and a friend can play and enjoy what the puzzles should have been in singleplayer. Overall, Portal 2 is still an EXCELLENT game. I recommend this one for everyone.
