We talk about this without anyone initiating another, but I'll try another shot

Currently there are 3 winning gaems with the same score
- King Arthur's Gold
- Mabinogi (private server)
- Terraria

From a quick search, I think King Arthur is a gaem that allows up to 12 people to coop and is suitable for one night. I dunno how hosting is, but it's a free gaem on Steam.
Mabinogi is an MMORPG, from that it can be said that, a server would need to be open at all tiems.
Terraria... could technically host many people, but even the large world doesn't have enough resources to sustain a large crowd (though there are ways around this issue if many users show up). We would also have to agree on stuff like not rushing bosses & going to hardmode before certain stuff are met etc. Someone would also still need to host it, and being a sandbox, it's not a game we can just play once and stop.

The standings may change if this thread encourages new users to vote, but doesn't change teh fact someone would need to undertake responsibility of being teh host. I'd help organizing non-technical parts
