Space Empires IV is one of the best 4X science fictiion games every made. It gives you lots of choices in technology, in a strategic universe that is varied but not overwhelming. I love its turn-based combat and strategic levels. It does have weaknesses, including computer opponents that are not aggressive enough once you get the hang of the system, and not smart enough in combat.
This is a fun medium/low complexity tactical wargame. The combat arms are well represented, with their strengths and weaknesses. You are generally on the advance, seeking to occupy certain objective hexes. The terrain is sort of a maze of wooded and open spaces. Infantry can move through the woods, while vehicles can't. Antitank missiles can be powerful, but you have to be in place and set up in order to use them. Tanks are mobile and powerful but more expensive in terms of force points. The scenarios are reasonably short and can be completed in an hour or so. Some parts of the interface are irritating. There are cut scenes of winceable dialog between the scenarios. There is no undo, and you can't save and restore. Thus, an errant mouse click can ruin a scenario for you. The only option is to start it from the beginning. You _can_ save a scenario and return to it, but you can't pick it up from before your mistake.
