Dungeon Village is in my opinion the best, because it provides a very nice mix of building strategy, Hero Management, battles and research. The 8-bit graphics you have to like (I love them), but it definitely has the advantage that they did not have too high demands on the hardware and is aging very slow compared to 3D graphics. The chiptune sound fits like always perfectly.
Cairo Soft offers its games exclusively in English, without proper language skills will you probably also do not enjoy using it.
