Alright, thanks for the response!

If I come up with a recommendation after a few more playthroughs, I'll let you know, cheers.

i dont include a list here, because i change and add map sizes then and again, but all map sizes generally work in multiplayer... its really not recommended to more than trible the default sizes for MP, because the matches become horribly long, and depending on all players hardware desync and lag will increase extremely. best to try around what works for you yourself...
if you have a size recommendation, i'd love to include it here too

Would appreciate more information about the map sizes involved in the mod, and whether they work in multiplayer.
