While taking a look at my collection of rules, I have noticed two things. I have, over time, drifted towards modern/sci-fi skirmish, although when I started looking for miniature games I would get all sorts: fantasy, historical, sci-fi, skirmish, large scale...
Also, I have not played most (maybe none at all) of the starship combat rules in my collection. I think this is due, in part, to my insistence in trying to play them with miniatures and a game mat, while the poor results of my previous attempts put me off.
Having decided to use the virtual tabletop more often, I have already set up a map to start trying 5150 Fighter Command, using Wydraz starship counters and one of Dave Graffam's space battle maps.
Besides 5150 Fighter Command, here are the other space combat rules that I have, in alphabetical order:
Astral Empires: Nova Command
Astral Empires: Battleshift
Starmada: the Admiralty Edition
USE ME Starship Battles
Does anyone have comments about them, suggestions about which ones to try first or even suggestions about other space combat games worth a look?
