What fun games are there for teenagers on the internet Im 12 and need a change from what games I usually do

Suggestions/Ideas for websites.
1: ROBLOX.com
2: WorldOfWarcraft (WoW)
3: RuneScape
4: AddictedGames (or maybe AdicctingGames)
I really recommend ROBLOX and RuneScape since I both play them. RuneScape's pretty good but ROBLOX is even better. ROBLOX has as much players as WoW does. That's better than awesome. I don't recommend WoW since you get only a 10 day-free trail and if you wanna play for real it's 5 dollars a month. You do get game cards where you get 1 month off but in ROBLOX you can chose from montly, 5 months, 12, months, or LIFETIME. RuneScape you can play free and do 5 bucks a month for a member.
I ALREADY PLAY ALL OF THESE GAMES ANY OTHER SUGGESTIONS
