Team Fun-tress 2
When I first got the Orange Box, I was only interested in playing Portal and Half life 2.
But once I had completed those 2, I decided to venture into the realms of Team Fortress 2.
I had no idea what the game was about, all I knew was that it was online only.
I got online and after getting my ass handed to me on a silver plater on MULTIPLE occasions, I got the hang of it and started to enjoy myself. I was soon t o find an English server full of fun people who didn't take the game too serious.
I had attached myself to the Scout class most, mainly because it took no skill at all to play, but as I got better and better, the more I began to loathe anything Scout related. I then glued myself onto the Soldier class and have been there mostly ever since.
The maps are well made, even if a little samey.
The classes (except scout) are all good and each one requires a different state of mind to play as:
The Soldier: Out to protect the innocent with his ROCKETS OF DEATH
The Pyro: The spy's worst enemy, a teammate's best friend.
The Demoman: Out for destruction.
The Heavy: Big, Bad and in control!
The Engineer: Protects the point, so you don't have to.
The Medic: Everyone's best friend
The Sniper: Your best back up
The Spy: The back stabbing, sentry sapping, sneaking GOD.
All in all, once you've found your favourite class, you'll find the game much more enjoyable, and finding a friendly server helps.
I do recommend, and it's sitting nicely in my top 5 favourite games list.
