Skyrim will undoubtedly get a lot of DLC and along with that, a lot more room to level up and pick new perks. As it stands, the max level a character can reach is 81 with 80 perks. Still being very far away from the cap, I've already noticed that there's a lot of similarity between characters in the later stages. I'm starting to put perk points into things I didn't think I would just because there's no where else to put them. I've become a werewolf with all of them because "why not?" Racial differences are pretty moot and choosing to focus on similar skills like two handed vs. one handed becomes mostly a cosmetic choice. I love the game to death but I sincerely hope there's some room for more tough decisions with future perks or perk trees in an expansion or whatever.
