I have a couple of ideas for new mini games as well as bringing some back, so here goes.
Hunger Games- This was brilliant back in the day and still is now.However, a lot of servers have took it away including this, and so, it would be great fun to bring it back. It may even attract new players because the mini game is depleting on other servers.
Battle dome-I mean, come on, it's a classic. It's great fun for all players and could again, attract new players. It also brings existing meep users together in teams and could also get more people on discord.
Death Run-I personally love this mini game. It's fun, attracting and all round a great game. I mean who doesn't like just a little bit of death run eh?
