Summary: I know a lot of people are saying that Team Fortress 2 is really bad but I think that its the best game in the package. Even though not as many people are on the ps3 version, it still, overall, has a pretty good turn-up. I didn't really like the controls for the game, but at least they let you change them to what you would like. One of the bad things on TF2 is that you can't zoom in unless you are a sniper and it's just a scope.
Summary: Five games in one. Five excellent games on one disc. Half Life 2 (along with it's two DLC packs), Portal and Team Fortress 2. All of the games are brilliantly made. The only real catch is the irritant frame rate on Half Life 2, that remains persistent on Sony's shiny black box.
Summary: Essentially 5 games for the price of one, it's a bargin, but not all of the games are that great. Portal (which I bought it for) is terrific and worth buying for alone. I have no complaints there and it's a great game. The Team Fortress 2 port is stable but difficult to get it to connect to the EA servers to actually play it, meaning you often can't. This is an earlier and more stylised version from the PC version, the look and feel of the game is quite different.
Summary: I bought this for Portal (as I absolutely loved Portal 2). Can't really comment as to the quality of the other games. Portal is not as good as Portal 2 but I still enjoyed what I have played so far. Plus 5 games for around £15 I thought was very good value indeed although a friend of mine has said they are slightly dated? Any way I think it's a good buy.
