Alright WoW stuff: Ulduar is pretty nice but Karazhan and Naxx were better and ToC had the more interesting boss mechanics (yes I said it, come at me bro)

Gnomer is a great instance. Oculus is fun. MoP dailies are great.

Wailing Caverns and Sunken Temple are terrible and Blizz can just remove them now and they will not be missed.

Non-WoW stuff:

The original LoZ is the best 2D Zelda. Overall the 3D ones were better (although they peaked early on with OoT/MM). Zelda isn't really an omg SUPER GROUNDBREAKING series to me but is enjoyable enough if played for what they are, which is running around with a sword and a boomerang and stuff.

3rd gen Pokemon was GREAT. It was also the last Pokemon game I played, though. 2nd gen is the best.

Vaporeon is the best Eevee evolution.
