Found an empty coffin in Rivenspire, so I (vampire) lay down in it for 10mins while I went and cooked dinner. Does that count?

I make some RP decisions but very select few. Mostly names, and races. After that, I do whats going to get me and my characters the farthest fastest, while looking amazing. (Must have that eye candy rolling.)

Yes. And almost all of my chars do quests exactly the same way. I am against slavery, weapons of mass destruction, killing when not necessary and similar. That is why I never completed few quests in ESO. Stuff that I did different than what I would do irl are killing mobs and enemies (duh), stealing stuff on a few chars and similar. But I refuse to kill last of the Kothrigi, I liberate Orsimer ghost army on Bethnik and Chimer ghosts in Stonefalls, I liberate prisoners in Shadowfen without absorbing keystone, I let goblins go from mine in same zone, etc. On the other hand, I send Valaste with Sheogorath every single time, sacrifice Sai Sahan and I let King of Worms escape.

Always.

I have three characters I actively roleplay with when I find viable partners, but even the other alts I always consider... "what would that character do?" when it comes to making a game choice.

Some of them will never play through the TG or DB storyline because they are honest characters (and I really wish visiting Abah's Landing for exploration and skyshard collecting purposes didn't come with a mandatory TG membership - change that, ZOS!). Some will play TG, but not DB because while they may on occasion be a bit lax about property laws, they draw the line at murder. And a few, very few, have done or will do both becausee they are just a ruthless bounty hunter, merciless pirate or a evil vampire...

Same for outfits, there are many costumes, but not all of my characters wear them all... same goes for disguises, some of my characters prefer to fight rather then disguise themselves, on other characters I try very hard to avoid any combat whatsoever and skeap past all I can sneak past... even though that may make their advancement a bit slower then it could be...

And it also works for dialogue options. Most of my characters are -either- strong and intimidating, -or- smart and persuasive; only two of them have both persuade and intimidate options available, due to being both smart and... scary in some way. And even so, I often don't -use- their options when I feel they wouldn't... my Orcess is big and strong, can easily intimidate people... but often does not when it would seem unjust to do so.

And none of my "good" characters would ever dream of leaving Valaste to uncle Sheo just for a few measly skill points! Why, that would be completely unjust! While for my more ruthless ones... gimme that book!

I even work on my crafting that way. That chauvinistic redguard alt of mine for example does gear crafting, because a warrior should know how to take care of his sword, but never learns provisioning recipes, because "cooking is a womans job", in his narrow-minded opinion. While my main bounty huntress is a master provisioner and also alchemist... things one needs to support herself out in the wilds hunting down a bounty, be it cooking what she catches, or mixing a healing ointment... or a poison, as the situation demands. (and is really vexed that the game does not allow her to mix poisons into food for... special occasions...). My librarian boy does woodworking and clothier to keep his staff and robes in good repair, but not blacksmith because he doesn't have the muscles for swinging a hammer in the forge - but plays with runes for enchanting instead. My Orcess does all the gear crafting, because she was training to become a forgewife before her banishment, making weapons and armor for her clan, and also has some provisioning skills, but none of that magic stuff like enchanting or potions. Et cetera.

I especially also like to think of backgrounds for my characters, even for those I don't RP with, just to have them. And to explain why they are how they are.
So my ruthless dunmer bounty huntress isn't on the evil side because she just likes being evil, its because she had a bunch of bad experiences in her past, from akaviri invasion to a short PoW experience, and along the way, fell in with some questionable people getting through them, and learned to deal with her problems that way, going from soldier to bandit to bounty huntress and naturally started her career as vestige through taking a bigger bounty job then she could complete.
My shy dunmer librarian boy on the other hand is not evil-ish because he didn't have such experiences, and rather sat among books reading about heroic deeds and such, and while he certainly wouldn't consider himself a hero, he does try to do the right thing... and ended up in coldharbour simply by being in the wrong place at the wrong time (he just could not resist taking that assistant job at the imperial library... at a most unfortunate time...)
And my orc amazon is as straight laced goody-two-greaves as any D&D paladin. Which started her adventuring career when she was exiled from her clan for following Stendarr because "Justice!" instead of Mauloch... and convnved her even more to always do the right thing, the heroic thing, to stand up for truith and justice no matter what, help the innocent, pursue the criminal scum, and so on (and she is somewhat disappointed that the PvP part of the justice system was never implemented, I'd have loved to play her as deputy guard, even though with my pvP skills, her capture rate probably would not be all that great... but being outfoxed by criminals -would- fit with her general "painfully honest but not the sharpest knife in the drawer" character, so... heck, I'd have loved roleplaying that too, and letting any "criminal" Player go if they just roleplayed making excuses she would believe... )
