Right let me start off by saying, to get the full experience of this collection you need the internet. full stop. My favourite game on this is team fortress 2. And id give this box about 3 and a half stars without it.
Half life and its both EXPANSIONS are pretty good. i had fun with them but if i found myself stuck somewhere i generally left the game alone for ages. but the game is really good if you can stick at it. nice graphics, nice gameplay, sweet guns. this game advertises saying it has 5 games in one, but half life 2 episode 1 and 2 are not that long and are really only short expansions of half life 2.
Team fortress 2. probablyone of the easiest to understang and get a hold of multiplayer games ever. you will know exactly what to do when you log on and play one game. you wont need a tutorial, but if you do your outa luck cos there is none, but you will find spot on people online that will hel;p you with any problem you may encounter, and there is ALWAYS a game full of people being played. graphics are awesome, weapon classes are awesome and get a few friends to buy it too and you will have a right laugh.
Now on to portal.this is the sole reason im saying avoid most reviews. the game is good yeah and quite inventive. but very short. the reason most people say this game is the best game ever is because of the ''internet humour''. because of the websites like 4chan and such most people who rate this game comment on the humour. and almost always only comment about ''the delicious cake'' at he end. if your a casual gamer and like your games explosive and full of guns this is not for you. but if you like a challenge then its definitely worth a go.
the game overall is the best value you will ever get. and is the greatest use of 13 euro ever. :)
