Final Fantasy 7 - It was a step back in every way... and after it came out Square hasn't really made a decent RPG since... and I used to buy and love every Square RPG.
Legend of Zelda: most after Ocarina of time - I thought Ocarina was ok. The rest has been a rehash of a game that i thought was alright and they've mostly been worse.
GTA games: Open world gameplay is great... but it sucks when the gameplay that comes along with it sucks... and everyone who wants to make a "Sandbox" game copies the crappy gameplay. Prototype and Infamous look like they might stop the drought. Last good "Sandbox" game I played was "Sid Meyer's Pirates!"
I loved GTA when i was playing it at a friends house... as soon as i played it i got bored after a few hours.
