FPSes in general. We've all seen the big guns and the brick walls and dull scenery.
I wasn't too keen on the HL Games either, infact Portal was the only HL game I was somewhat keen on. Nomatter how many forced jokes they stuff in 'ere I'll always love it.
PS : I reccomend you get your Flame-Armour on people.
PPS: After playing them for an hour and a half, I started to like HL, but I kinda thought it was too dull.
EDIT : I didn't like Ep 2. It was basically EP 1 except without as much of the action.
Oh, and are you comparing Half-Life to Multiplayer FPSes? 1 Thing fo' sure, as soon as it hears the word's "Multiplayer" Half-Life has a heart-attack and dies. So that's not very fair comparing a mostly single-Player game to very Multiplayer constricted games. Most of the work was built into single player, and the Multi-Player designers were probally starving monkey's.
Dead Space, It just wasn't scary as people made it out to be. I may sound like a twat but I beat the entire game sitting there on my couch with the lights off (A friend reccomended it to me) and beat the game simply staring at my screen eating a bag of chips and wasn't scared once.
JRPG's in General. A game where our main character gets dressed by stepping on a mine in his closet full of old 80's fashion collections and styles their hair by dipping it in a bucket of led paint ... And I think turn-Based-Combat is utter shit.
Online FPSes. A game where I have to rely on some 13 year olds biting their toes as I storm through the enemies base with the alarm on looking for first aid kits ... Is really repetetive when I die for the six-billionth time.
Nintendo games. A company that takes an old classic, gives it a 2.5D atmosphere, and a terrible multiplayer feature just doesnt work. I dont like the multiplayer, characters bounce of each other and power-ups are basically designed to go to all one player. Also inventory management is utter SHIT. I dont want to use s mushroom on the whole team when only I need it!
There, basically every single game/genre I hate (Especially games that claim to be scary (Bioshock,system shock, Dead Space, The path)and aren't) ECT ECT
PPPS : I, myself am a Valve fan, I mainly liked their early games (Half life, Ricochet, HL2, ECT ECT) But I agree, the HL2 Ep's and HL2 are very dull, I stopped playing it about 4 hours in and found myslef playing ricochet and found it waaaay more fun.
