I dont have suggestion for the game but for discord. In the evenings the voice chats(hangouts) are full, and people who want to play together and be in voice just cant or need to open their own discord servers. I think there are ways with discord bots to make one room, and when you enter that room new hangout chat is made (etc Hangout#140) and when all 4 of players leave that hangout chat, it gets deleted ;) <3
