Thinking of a list.

Gotta question for you all. I am trying to define the western computer rpg in my head by companies that currently (or used) make them. The obvious starters are

Interplay

Bioware

Bethesda

SSI

Mindcraft

The last one might really test your crpg chops. Anyhow, I want to extend the list. Got suggestions? Remember, western crpgs. No Square Enix.

Edit: adding and manipulating the list a little

Interplay -> Interplay/Black Isle (by suggestion of Frame_Dragger)

Obsidian (courtesy of AlmightyMax, interesting because their business is almost entirely based on Interplay's and Bethesda's products)

Wizards of the Coast (as much as I hate mentioning them)

Origin (courtesy of luc11044)
