I recently discovered this :
https://github.com/Return-To-The-Roots/s25client

it is a remake of settlers 2 , with better graphics and support for multiplayer games. You need the original game to play (i assume for graphics). It has a lot of awesome features. The software will compile on windows, mac and gnu/linux.

I really wanna play some multiplayer settlers 2. So I was wondering is any of you would be interested in that also
