Star Wars: Knights of the Old Republic 1. Wonderful interface and controls. An example of how a PC and Xbox port can coexist happily and successfully.

Neverwinter Nights 1. What the HELL did they do to this in NWN2? Everything worked pretty damn well the first time around!

Star Wars: Republic Command. Agree with Monk, this was a well done interface. The game itself was rather unpretentious and fun.

Starcraft. As much as I am horrible at RTS's, they did a really good job polishing this game up. Everything had a keyboard shortcut, the UI was easy enough to understand and use.


Hall of shame

Elder Scrolls 4: Oblivion. THE poster child. They screwed this game up so hard it physically hurt me to try and play it. Good lord. Even WITH the darnified mod, it's still damn awful. Complete opposite to KOTOR1, how NOT to do a dual PC/console port interface.

Dishonorable mention: Fallout 3. More of the same Bethesda, more of the same. *sigh*

NWN2. Corollary to NWN1 above. They really, really screwed this up royally.

Fallout. Not intuitive at all, inventory system was bollox. Loved the game, but ugh.
