Games that were graphically impressive for their time, but are ugly now.

[JWeinCom]

Mortal Kombat- The mocap stuff was nifty at the time, but sprites aged much better.
FF7- The out of battle character models are kind of ugly. Sort of ugly in a charming bulldog kind of way, but ugly nevertheless.
Skyward Sword- Not quite ugly but I originally played this on a 480p TV and it looked good. When you try it on a larger higher resolution TV the flaws become much more noticeable.
