It even has vestigial trade, diplomacy and culture elements. It has a staggeringly comprehensive research tree, with no chance that a player will be able to complete all of it in a single game. It features battles with first dozens and then hundreds of ships all blasting the titanium out of each other with mass drivers and lasers, while swarms of fighters and bombers flit in and out of the fray.
It’s a real-time space-based 4X game where you gradually spread the tendrils of your empire out from your home planet into the galaxy at large.
