When I got old, I don't like playing online games "just for fun" anymore because I'm already a mom (lots of house chores to do) and I consider playing online games a waste of time. Today I only play online games where I can get something in return (like real cash). Though sometimes I do play classic nintendo games like Loopz and Othello on my son's old gameboy (which he no longer uses) but only to pass the time or when I can't sleep at night.
You should try candstand.com . I wish they had OMGPOP still since their games were fun and I liked their customization.
