I don't know if gaming counts. I've invested in the novablitz ICO. It's card game like Hearthstone. Cards behave the same way as cryptokitties and such. According to devs users would be able to trade cards easily and without fearing that you bought a counterfeit card. Tokens can be staked to get new cards whenever they are added to the game.

Devs are pretty active on the telegram if anyone has questions t.me/novablitz and on novablitz.com
