Left 4 Dead 2 - I don't have words to describe how utterly boring, gimmicky, rushed and stupid this game was.
Quake 3 - MP Only? Really? REALLY?
DOOM 3 - Most people already expressed the same disappointed on how pretty it could be, but in the end just a tech demo and not a game.
BioShock - Raved about by reviewers, I ended up just watching a YT video with all the story bits and cutscene's because as a game, it's just drivel. No matter what I do this game just gives me a damn headache when I try to play it.
Borderlands The Pre Sequel - This is not the Borderlands I'm looking for, moved along. I'm still angry as hell about this terribad game I pre-ordered with the season pass... This was before you could get refunds on steam, and this is the only game I ever really wanted a refund for (and I bought Nerves of Steel). Steaming pile up there with A:CM. I hope Gearbox's next game flops and they finally go out of business.
Duke Nukem Forever - how can you not be disappointed in this.
Fallout 4 - Skyrim is a masterpiece of an RPG compared to this lackluster tech-demo + bad minecraft simulator. I am a huge fan of all things Fallout, I am sad to say that Beth has killed it for me. Fallout 3 was tolerable because Obsidian made the real Fallout game with NV, and we could port F3 into that engine with it's mechanics. Dumbed down garbage for the masses of sheeple without any concept of what an RPG is.
