I just love it and it's free. A lot of options, interesting game mechanics and technolgy tree, a lot of units and civilizations. The design is beautiful and gameplay it's smooth. There are enough mods (civilizations, maps, other stuff) that you can add to this game. I only played at "very easy" and "easy" levels though ... Thank you for this gem!

Great. playing on some oldish PC, working fine. playing on time multiplier x 1 was a recipe for 15 min defeat. x 0.1 worked a charm, although everything is really slow there's enough time to play around for first time especially. AI is very organised.

Great game, essentially a free and open-source version of Age of Empires III. Its only limitation is that I think it should have an in-built demo mode to show beginners how to play the game effectively. Granted users can search for a video demo in YouTube, but still I think this would improve the game. Plus I also think that pressing the Esc key should pause the game, it's a popular keyboard shortcut for pausing games (e.g., it's used by OpenRA).
