I usually don't like FPS games, I find them mindless and shallow. But sometimes a game comes around that completely absorbs me, and that was the Half Life series.
Due to my long standing addiction to WoW, which has subsided on the past month or so (raiding is boring, I still arena but I'm mainly waiting for the xpac), I never played many other games on the side. I have an obsessive-compulsive behavior when it comes to gaming, and I usually pour myself into one and only one game at a time. And when that's an MMO, well, I miss out a lot of other games. But I'm trying to correct that right now.
Half Life has that one feature in games I'm most interested in: storyline. Being a hardcore RPG fan, I'm a sucker for good stories. I don't even care if the controls are bad, or if the graphics are lame. If it has a great storyline, that's all that matters. And so it was with HL. I enjoyed the games very much. The story is compelling, and made me want to keep going just to know what would happen to the main character and the rest related to him. The weapon choices were fun, but they weren't a defining factor (but I did have a fav. weapon, the standard, trustworthy shotgun, nothing more satisfying than annihilating living people AND undeads in their faces with one shot). The gameplay is also satisfying, it rewards smart moves and tactics over mindless, careless "rain of bullets", although I did resource to that a couple of times. Having a quick save/load helps a lot too haha.
I'm not going to go through the storyline here, because if anyone who's interested in playing reads this, I want him/her to do the discovery on their own. I'm just going to say that is completely worth it, and there's a reason why this game is part of the "must play" list.
And in a more personal view, Gordon Freeman is hot. Despite the fact that you NEVER see him in the game, and he never, ever talks, he's still a physicist researcher who kicks ass with weapons. Like a jock with brains. I bet he's as fast to kill zombies as he is to solve difficult equations. If I was Alyx Vance I'd have screwed him the first moment I had the chance. Ok, I'll stop.
