It is an outstanding game. The amount of possibilities you have is pretty much unlimited what you can play or how you play.
Some themes of LegacyClonk are Medieval, Fantasy, High Fantasy, Vampires, Western, Modern Military in different variants, Space and many more. It got pretty much everything.
A summary of the genres that you can play are: Settlement, Small Melees(PvP), CO-OP(PvE), Adventure, Tower Defense, Team-Based PvP around objectives.
The random map-generations keep the game fresh and engaging, in Settlement aswell as in PvP.
The controls are a bit hard to learn and have many hidden things you can do but it feels really rewarding when you get better.
