Just because they produce great games doesn't mean you should hate them. It's extremely immature to start fighting against something that will have no immediate effect on your life.
Valve ideas are often used because they add creative and gameplay-altering changes to the game, unlike halo which just has generic guns and vehicles.
Team Fortress Classic wasn't good, and valve made that.
hand to hand combat.
The only thing I dislike about Valve is that they don't port their games to the PS3. ;(
Which explains why PS3 has no games.Because valve hasn't unloaded their stuffloads of games on to it.
They should make a game where you play as a mechanic with a big wrench(for hitting things) who fixes cars and battles the evil robot empire.
Leaning towards rachet and clank there a bit.
