Thx for this question.
It is possible that a beer pong game in Decentraland could be a fun and engaging activity for players to participate in within the virtual world. It could potentially attract more player and create a social gathering place for people to interact and compete with each other, like the Rock paper scissor. And its opensource, so everybody could use it on their land / realm.
I like this idea! I would love to see more mini-games added to weekly events! It is fun to be able to visit your friends at these events, what if we could enhance the experience by having things to do like a beer pong game? I believe it will immerse more users and attract more users to these events when there is more to do other than chatting and auto-dancing.
