Elder Scrolls online is very fun despite the bad rep it got in the past. I have so much fun playing it and the player owned guilds are super neat in that game! I have seen a lot of awesome role play guilds that focus on thieves guild or dark brotherhood etc. They also have their own marketplace and neat little merchant guilds etc.
Not to mention there is like a billion quests and they are all very interesting! I really love this game even though I am low level I have 80 something hours into it just because I love to explore and rp and do side quests xD! Its a great game and I would advise trying it out when it is free to play again!
