Free Online Game MMORPG?

looking for an online game. i liked wizard 101 so thats all you need to know. something i guess like starcraft or warcraft or that wizard game. just wanna play in evenings when kid goes to sleep and hubby doesnt give affection haha. maybe theres an online fantasy game where you simulate a loving family with no problems? or maybe a pirate one where i can go hunt for treasure and kill people to let my frustrations out
