It doesn't get any less complicated than that. What video games do you really despise (or dislike) that everybody else in the world seems to like? An explanation is optional.
Here are mine:
Gears of War
World of Warcraft
Guitar Hero/Rock Band etc.
Diablo I & II
Most of the Tom Clancy games
Anything after GTA: Vice City
Most of the Medal of Honor games
Most of the Call of Duty games (up until Modern Warfare)
Technically it made great use of the Source engine. Motion blur and portal rendering is excellent. My gripes with it is that how unsatisfying it is playing through. It is simplistic in design but the repetition of doing the same thing every time is just monotonous. After completing it and trying it again after the Steam For Mac emergence, I thought of style way over substance.
(SPOILERS) I was positive on the twist in the game after completing the chambers. I would have felt better if Chell died in the fire. Leading up to GLaDOS only recited my view on playing. Fighting her was just too easy when it intends to evaluate my performance. I completed that no problem. The ambiguous ending and the credits song only left a bad feeling.
My experience got spoiled too with Valve fanboys in my school singing the song and talking too much about "The Cake is a Lie" meme. For moments I only believe the game's fanbase exists not because of its gameplay but its "charm." But that's my problem though.
I believe it's Valve's worst game. I sure hope the sequel improves and makes the puzzles mind boggling not like its original.
I might have said the same to Team Fortress 2 but at least the gameplay is fun.
-Call of Duty Modern Warfare 2 " It's shits for the birds and was waste of my 60 bucks. I want it back man.... All my friends forcing me to play with them on stupid search n destroy while I get a good 3.34 kill/death ratio-- it's fckin bullocks"
-Almost all of the NFL Madden games, even though I like the ideas of them.
-The Halo Reach Beta " It's great, but it rips almost every game off while I'm hearing peeps saying it's original."
-The Damn NEW Power Glove Controller " If you think that's cool, wait til ya play it."
-Street Fighter IV-- but I like Super Steet Fighter IV better for some reason...
