Not completely fair but both games combine FPS and RPG elements and both games take place on a wasteland. Borderlands is faster paced, yes, but the game share many similarities. Limited inventory space, quests, experience points, levels, skills, looting...it's all there. And IMO New Vegas does everything better. As good as the game is at every turn I find myself thinking 'this makes me think of New Vegas...man New Vegas was a mind blowing game...I wish this game was New Vegas'. But I am enjoying myself.
