Two Worlds II - Worldmerge Mod
Here's an interesting Two Worlds II mod that "combines the Two World 2 main campaign, the eleven multiplayer adventure maps and the whole Pirates of Flying Fortress Expansion into one coherent, newly balanced singleplayer gameworld". I've no idea how well it all works but it sounds worth a look if you were planning to return to 2W2 at some point. Here's the full intro:
Worldmerge - though done without SDK/Toolkit - combines the Two World 2 main campaign, the eleven multiplayer adventure maps and the whole Pirates of Flying Fortress Expansion into one coherent, newly balanced singleplayer gameworld. It ties everything together with a very long new questline sending you all around the world of Antaloor, even to the most hidden corners. You will find three new difficulty levels (Novice, Expert and Master) with various tweaks and enhancements, each for a female or male player character, that bring a lot of extra challenge. In addition to that many great mods by gifted modders from the Two Worlds 2 community are included (see details below). The singleplayer game time (compared to the 45+ hours of TW2+PotFF) is easily extended by more than 15 extra hours (25+ if you choose the Master Difficulty).
