When he will finish, you will be able to play mm6-8 on modern systems, with better graphics/resolution and support for mods.

Author goals are: (1) Fully reconstruct the original engine. (2) Update render to modern Direct3D 10 graphics maintaining back-compatibility with mm6/7/8 resources. (3) Create a base for the community which can be enchanted by everyone willing to contribute, e.g. keep the engine open-source for programmers and provide various flexible tools for artists and modders so anyone can create his own adventures in the world of Enroth. (4) Additionally, there are some ideas for multiplayer.
