EV was quite good; Starsector is leagues ahead of it in terms of combat, comparable in terms of user mod-ability, and (so far) leagues behind in terms of exploration, environment interaction, plotline, etc. (Though some mods manage to address that...)
But, well, that's kinda what Alex is working on next, and it's still alpha anyway. Totally worth getting regardless of that 'alpha' tag; I got my money's worth back when the campaign mode didn't even exist and you couldn't outfit your ships in missions, and it's only gotten better since then.
(Speaking of EV Nova, my favorite thing was always turning a Polaris medium freighter into a full-on warship. Had to do the right plotlines to get the upgrades that let you mount guns at all, and you pretty much had to know about the wormhole network to bypass the hostile Polaris military outposts so you could buy the right ship... but it had amazingly strong shields, was quite decently maneuverable, and - with all the cargo-to-weapon-space conversions you could buy - had room for an amazing supply of missile weapons, with enough cargo space still left over to pay for a complete munitions restock in a single delivery run. Spamming hellhound missiles was a great way to blow up everything in your path.)
