TheRatKing said:I'd hate to call Oblivion an adventure game. Although it is an adventure, adventure games tend to be about solving puzzles and actually thinking. Oblivion was generally a hack and slash with some very simple quests. I would call it an ARPG lite.
Edit:
I would probably call The Witcher an ARPG, and Fallout an RPG.
I would just call Oblivion, an Action Adventure with RPG elements, or First Person with Swords .
The Witcher is an ARPG, but it's more an RPG than Oblivion.
