I think it needs to be like Morrowind. If it is like Fallout or Oblivion it will not be good IMO. I love Fallout but I don't want a TES games to feel like Fallout. Oblivion was alright, but I much preferred the feel of Morrowind.
I count count the nuber of times I've thought that ~in reverse.
I don't understand the player mentally that desires the game to place restrictions on you. This is a role-playing game. Play that role. I shouldn't be forced to go pure mage because other people want too. (looks at other RPG's such as Dragon Age.)
I don't know if I can explain it well enough, and ? way through, I think you would begin to understand that the idea is so totally alien that you would not want to hear the rest. ~This has been a common reaction here over the years.
In short though: The PC is considered to have an aptitude for their committed profession, and while (in some games) they can learn skill skills out of the ken, these skills don't come naturally and are harder to master. The idea of challenge through limitation is an old one, just look at bottled ship building. Anyone can build the model, but the enjoyment of it, comes of building the model through the little opening of the bottle, a window into that inner space; PC's are like the little window into their world, and each PC is a different shape. No limits, = no bottle = no fun.
**Of course this assumes that you are out to change the world, not just explore it at whim. I can understand those that want to just wander free and do whatever comes to mind... and why restrictions would ~restrict their fun. Like you said, its a different mentality.
Actually that's incorrect. If you want to actually get down to it perks were taken from D&D. (feats) The idea for Arena came from a D&D campaign the devs were playing. Daggerfall had perks, advantages/disadvantages. It came out in 1996. Fallout 1 was released in 1997. So, no. Elder Scrolls was/is not copy/pasting from Fallout.
Actually Fallout was originally based on GURPS, and a Dev named Chris Taylor was credited with inventiong the Perks system; and Perks have no disadvantages. Feats are are D&D skill training.
