RSMC: The Third Age (RuneScape in Minecraft)
RSMC: The Third Age brings RuneScape-style worlds, skills, trading and bosses into Minecraft, and runs as a Forge mod for 1.18.2.
What it does
Players of the mod work through 24 skills that level up as they train, and the content covers an in-game economy with a Great Exchange for buying and selling items between players. A trading screen lets two players exchange items directly, and the economy works on servers with players online.
Content includes bosses such as the Barrow Brothers and Godwars, abyssal demons and dragons, mini games, dungeons and treasure trails. The author lists more bosses and dungeons as coming in later updates. Single player and multiplayer both work, and the mod can run on a single-player world or a server.
Installation requires one other mod to work, and the mod is built for Forge 1.18.2 with Java 1.18.2 specified by the author. Both the server and every player need RSMC installed, since the environment is client and server. The source code, issue tracker and wiki are public, but the license is All rights reserved, so the code is not open source.
