Nearly every third-person shooter is a fine example of the things wrong with videogaming. The only exception is Vanquish.
Half-Life is a terrible game that ruined the FPS genre, and almost every FPS made after the early 2000s is equally bad, if not worse.
While we're at it, most of Valve's games are average or worse. Portal is excellent, however, as is the CS franchise (and many of the other games that are simply repackaged HL1 mods, like Ricochet).
Every Bioware game made after Neverwinter Nights is bad.
The entire TES series is mediocre despite being built on a great concept (I haven't played Skyrim but I own the other four).
Every single console-based FPS is terrible, from Zero Tolerance to Goldeneye right up to the present.
I have never liked a single Rare game that I've played outside of DKC. Diddy Kong Racing sucks, their shooters suck, Battletoads sucks, Killer Instinct sucks.
Bioshock sucks. So does Uncharted.
Sleeping Dogs was a bad game despite the excellent setting.
The JRPG genre consists primarily (but not exclusively) of derivative garbage with minimal gameplay.
I think that should sufficiently alienate myself.
