I've marked out a square area at the area around
(84, 219) (just on the other side of the hill opposite the spawn house). I'm envisioning that this might be a good place to build a Classic
Spleef Arena. Alternatively, we can make another type of arena somewhere, if we want. (I figured that it might be nice to have it close to spawn, but I can totally understand if we wouldn't want that. It can be made underground if people want.)
Classic Spleef is basically a game where players attempt to dig out the blocks underneath their opponents' feet and cause them to drop into the water below. The last person left standing is the winner. It can be quite fun :D
I haven't explored the other Spleef game types on that page, so if anybody thinks another game type would be better, feel free to mention it!
I also made sure that when marking the boundaries I didn't destroy any blocks that were already there (other than grass), so if we decide not to build there we can just remove the cobble/netherrack that's there and it'll be just the same as before.
Very interested to know your thoughts :D
