Slow, very unrewarding game. No point in it, no pay off, sense of achievement, but insanely grindy. Every battle you must replenish entire army after it and are repetitive, with no reward. They increase requirements for resources for research or to upgrade something, or workers needed to produce those resources all the time, yet you get one additional worker every 10 technologies researched or so. At least Chinese pay to win give you stuff to do even without paying, this one just makes you wait
