Bethesda raised the level cap and added perks with each of the three main add-ons for Fallout New Vegas, but not for the last, much smaller one, even though it introduced several new perks.

The current level cap in Skyrim seems odd, we don't remember any other game with a cap that isn't a whole number. They would have to either introduce new skills or allow progress past 100. (We have found a way to get a Sneak Skill of 102 in Oblivion, but can't see any real change from it.)
