Sequels are the game that tend to make the most money in this industry, so it is pretty much expected that every big game will get one or more sequels. It can be great when a sequel turns out as good or better than the original, but it can be devastating when it doesn't. These 10 games didn't to live up to the quality of their predecessors, and failed to meet fans' high expectations.

PD:Zero, my cousin who was a fan of the series turn it back in the same day he purchase it. I played for a few hours and hated it.
Bioshock2 was good game but it didn't seem to live up to Bioshock1. I know 2 was developed by a different studio.
Sonic the Hedgehog (2006) didn't live up to Sonic Adventures 1 nor 2. The whole storyline seem stale, long loading screens. I beat and end up giving it to my cousin because I knew I wasn't going to replay it again. It was the beginning of a bunch of crappy sonic games. Okay maybe Sonic Heroes was the beginning but wtf they both sucked to me but Sonic 2006 seem to suck more.
DA2....still haven't brought it yet maybe If an ultimate collection comes out if I can catch a 10-15 price tag then maybe I'll get it.
Agreed with BioShock 2. Same as above, not a bad game, just not in the same league as the original. That lady got damn annoying. I hated listening to her talking the entire game.
Disagreed with MW2. From what I remember, the campaign was similar to CoD4 and Spec Ops were plenty playable. If it had a short campaign and you paid $60, ok, be disappointed. Be patient and pay $10-15 and it seems much more worth it. Already knew CoD MP was trashy, so that didn't disappoint. They mention not caring about WaW. That should be the one on the list. When I got around to playing it, it felt like three quarters of a generation behind MW and Blops.
Off the top of my head anyways.
