The Betweenlands Experience
A simple modpack which is solely betweenlands-centered, having only mods adding to the content (slightly) and ambience of the betweenlands.
The base mods (while I already knew about most of them) were mostly selected by someone else, and this modpack is meant to be used on a server and have been selected with multiplayer in mind (As its name might imply, it was originally meant for multiplayer and is therefore supposedly able to run correctly and without any major issue on servers)..
Important note : think about lowering footstep sounds when playing; by default they are quite loud
It is true that this pack ressembles Rubber Room Classical Edition (which I made earlier), but Rubber Room Classical contains some mods and configs which aren't specifically tied to the betweenlands, while this pack contains none of that.
The only true extra content in this pack is added through small or rare structures (which won't impact the overall betweenlands experience), as well as betweenlands addons such as betweenlands redstone mod and betweencards; there is also a custom configuration for antique atlas allowing this craftable-minimap to be obtained within the betweenlands (already installed when you download the pack, link to the original page below under the mod and ressource pack list).
Do not forget that the betweenlands has advancements, as well as an official wiki which is linked on their official curseforge mod page =)
