You don't want inherent restrictions, as you think the player should restrict themselves, but like the Great Houses, and like that the player must choose?
Self-imposed restrictions are a crutch. If the game cannot give you proper feedback to what you're doing (including what race you select), then it's failing. If you don't spec into magic skills, then you shouldn't be expected to get far in the College of Winterhold. If you play a Khajiit, city-goers should be extra-suspicious of you. Etc.
You should rstrict yourself based on class and race and how you want to play. The game should restrict you faction wise. If you join the College you cannot join the Companions. You should also be limited by your skills in advancement threw the guild and you should get some great reward at the end, and people should recognize you are the leader of that guild.
Yeah, it would be interesting if, because you were in the Mage's Guild, the Companions wouldn't accept you, or let you go very far.
I would like that, but I wish we had more factions for options sake ten would be a good number.
Yes. In Skyrim we have the civil war, so I think they tried to address the issue a bit, but it's nowhere near as good as Morrowind's Great Houses were.
On the topic of character individuality, being able to smash your way through the Thieves' and Mages' Guild questlines as a heavy armored two handed warrior is kind of lame. I would like to actually be forced to be a fighter, a mage, or a thief to be successful in their respective guilds. I think Beth had the right idea in Morrowind requiring proficiency in certain skill sets, as well as adequate contribution to the guild, to advance through the ranks.
Its a step up from Oblivion but its still behind Morrowind.
You should be able to go threw the College as a battlemage.
But I agree you should be at a certain skill level to advance, it makes no sense a thief can be arch mage. I would like a skill requirement before you advance your rank. See above.
