Fun 3d virtual worlds 12+ no download

I really LOVE virtual worlds and I'm in need for new ones and am outgrowing/getting bored of other games I play. Here are worlds I checked out:

Smeet Seemed soooo lame
Smallworlds Is fun but has short attention span 6 out of 10
Club Penguin .... mm mm NO Too old for it and lame
Spark City world Don't get me started lol


I've tried a few others but none have caught my attention enough to stay. My tastes are like sims and worlds like Wizard101 and FreeRealms. Thank you so much for helping me. :)
