I'm working for a long time on this project, and a new round of the game is just starting.
Empires in Space is a turn based 4X (Explore, Expand, Exploit, Exerminate). Exploration and expansion are bit like in Civ 4.
Colony and goods management is a bit like in the Anno series.
The big differences to those is that Empires in Space is a massive multiplayer title and played with the browser.
When mentioning browser, I think I have to directly add that it's free, without some pay2win option and without advertisement
6 turns are evaluated per day, but things stack up for multiple turns and everything is balanced so that a single login per day suffices. If you are a 4X enthusiast (or could become one), I'd be happy if you took a peek at the game:
