In, RPGs, I always like the ability to solve quests through smarts or diplomacy.

In my ideal Skyrim, there would be 3 ways to deal with most quests: Fighting, stealth, or diplomacy/puzzle.

What do others think?

indeed.

Im a stealth person myself, I played splinter cell religiously and wanting to sneak through games has just stuck.

Yup, and don't forget good and evil paths.

Yeah, it would be cool if you could always switch sides when the quest giver wants you to do something unethical. I think there was one quest in Oblivion that required you to kill an Argonian and take his heart to the quest giver, but you also had the option to collect the heart from a random Argonian's body instead of murdering the target.

I hope the karma system and good or evil term go away.

You attend to a quest, you do it as you like or as the other parties involved in that quest like, and in doing so, you gain some personal benefits and /or affect your reputation with some involved parties.

That's all.
