All of them! I played since 05 when it came out. I heard about it through one of my Toontown friends.
I love chatting with new people who are ALL awesome on MyVMK. I also love playing games and earning credits to trade with people. I loved the Haunted Mansion game and I'm super excited to start playing that.
I'm also excited for quests. I didn't do a lot of quests in the old VMK since I was kind of young and didn't understand, but I remember I had a car, and deep sea diving.
It's something to do when I'm bored around the house. I don't have much else to do, so it's a good way to pass the time, and it's a nice reminder of all the good times I had as a kid/in the actual parks.
