You cant use OP4's CD key with steam, it's some gay thing they've implemented saying "because it comes with Half-Life, you can't use it again", or some crap.
I've tried it before, unless it's just me getting the shaft.
Ehhhhh, lets add Half-Life series for the sake of it. Half-Life is something I cant play over and over again, which is why it initially didn't make my list. But I have to give it some sort of cred.
Another good, but kinda stupid story one. You go to a boat and you're trying to take pictures for god knows what reason, and somehow you don't die because apparently the Marines are too stupid to check the locker you're hiding in, even though you're clearly knocking on the wall to get attention. Some stuff is funny, like when you can get in a box, but other than that, the story is retarded. Especially the end, where it does all that "Fission Mailed" crap. Alls it does is give you a headache and leave you wondering why you spent 50 bucks on a game where you go into a room and see a cut scene that lasts 30 minutes, and have some guy tell you "They did the mash, they did the monster mash. The monster mash, it caught on in a flash."
It's a good game, but I'm not sure if I could keep playing. I got about half way through and it got kind of boring to me. The plot is kinda weird, too. I mean c'mon, you get to an island, your ship blows up, then this black guy calls you up and is like "Now this is the story all about how, my life got flipped, turned upside down. And Id like to take a minute just sit right there, Ill tell you how I became the prince of a town called bel-air. In west Philadelphia born and raised, on the playground where I spent most of my days; Chilling out, maxing, relaxing all cool, and all shooting some b-ball outside of the school. When a couple of guys who were up to no good, started making trouble in my neighborhood. I got in one little fight and my mom got scared, and said you're moving with your auntie and uncle in bel-air."
@habboi: That has to be the best part in the game.
When I was playing Far Cry, I just got to the part with the huge ass monkey things. I wasn't expecting it, and when one ran up to my it scared the shit outta me, and I proceeded to yell.
