I realize that TES, as a series, is often too big to please everyone. Some people like adventures, others like fighting, others like realism and role-playing, and the list is endless. However, most people have two things in common:
- They prefer their character behave a certain way (good, bad, ambiguous).
- They prefer their character have skills and abilities - as well as weaknesses and vulnerabilities.
Furthermore, if you gave characters a certain number of perk points to spend at the beginning of the game, we would have the ability to create that unique and custom avatar with its own background that so many players lamented the loss of when it was announced that attributes were out. There was a lot of thought that the lack of attributes would kill unique characters and that perks would be a sorry substitute. To the contrary, I think breaking free of attributes actually allows quite a bit more customization for characters, but only if the perk system is made robust enough to compensate. I think perks have more potential, but most of that potential is yet unrealized.
So that's my greatest wish for Skyrim expansions and even for TES 6. Take what you've started with Perks and run with it.
Add in trees for Acrobatics, Athletics, or all sorts of other skills and attributes that have been removed from TES and give us back that old -time Role Playing game that we all love.
The beautiful thing about perks is that they can't take anything from the game. Don't like it, don't use it. By having enough perk trees (and points to go around) each player can do whatever they like, and not be bothered by the existence of the trees that they prefer to ignore.
