ONE BOX TO RULE THEM ALL!!
Half-life2: Nothing to say about this game cause we all know that this is the greatest FPS game ever in the history of mankind. Don't call yourself gamer if you never played this game before.
Half-Life2 Episode1: Well, the first episode was a little bit weak comparing to the awesomeness of HL2, but you know when there is a Half-Life in the name and there is a company called Valve, nothing can go wrong.
Half-Life2 Episode 2:
The saga continues in the Episode 2, and oh boy, what an episode it is! It feels so complete in all the way. The story in this Episode is awesome, I mean legendary. The outskirts of city 17 is well put. The atmosphere was great. And there are so much varieties in each level designing in this episode. I think Alyx is the most realistic girl in game universe. She feels so real!! Thanks to source engine and valve, of course.
Portal:
Ok, who wants a cake? Yes, we all do. And Apreture Science enrichment center provides the excellent cake with great dark humor.
Seriously, the game is a bit short but it is awesome in every way. And speaking of short, the story is short but you can get more puzzle solving and gameplay from user created maps. So its not short at all.....
Team Fortress 2:
Oh, what can I say.....'teh' most awesome MP in this year. Sure. MP game of the year? Hell yeah again. The game is beautiful, with the cel-shaded graphics and cool animation, the game is superb. To me, CSS and DODS just lost to this baby. And I'll play it over any previous MP games.
There are 9 classes, as you may know already. And the game is greatly balanced. And its really tough to balance a FAST-PACE FPS games with 9 classes on each team. And Valve did it.
Its hilarious, awesomely funny. And you never gonna feel bore playing this game, never ever!
I just found my next MP for over a year.
All in all, Orange box is a must buy for any PC gamer. If you have a PC, then get it. If you have a 360 then get it on 360. If you have both, get it on both! If you have none, then also get it!
