I never got around to playing the Half-Life series until only recently and man... I had no idea what I was missing!!! Best story, gameplay is perfect and it still holds up to todays standards. Shit, I even got scared when I saw my first fast zombie! If you havent played it yet then your seriously missing out.

Just bought both these series during the sales and its was worth every penny! I totally enjoy the incredible experience this series has to offer even though the games are a bit dated. The story line gets you so engrosed in the game you cant hardly stop playing and if thats not enough Bioshock puts a totally new spin on the orginal fps with plasmas! If you've always wondered about giving this game ago and haven't gotten around to it yet I definitely think you should put some time aside for this.

Btw I'm definitely getting Bioshock Infinity now =D!

Although still similar to MW2 this game does hold its own with great gameplay and new play styles such as the killstreak system which is 100% better than in MW2. Heck you can even be a juggernaut if you good enough in multiplayer and nothings better than watching people flee in fear when your chasing them in your suit.
