3. Little Big Planet
Little Big Planet has hands down one of the friendliest communities online. It's so good, I could count the bad experiences I have had on one hand. On the surface it might seem obvious to call this a kids game. You might even scoff at the notion that mature gamers actually even play it, but you need only look at the toxic online community of Minecraft to see that kids can be the worst offenders for online abuse. Entering a user created level with strangers is an excellent way to make friends and the rating system promotes friendliness. Little Big Planet is a community driven game that improves as you go along. With most online games turning into online battlegrounds, it makes for a nice change of pace.
