might i suggest ufo extraterrestrials its an excellent turn based strategy game i probably have at least a hundred pc games its one of the few ive finished actually finished it a couple times

Try Kings Bounty: The Legend or the very similar but newer Kings Bounty: Armored Princess (personally I got both of them from Impulse - super convenient).  They're both great; I prefer the first (KB: The Legend) because I preferred it's alternate magic mechanic (box of rage vs pet baby uber-dragon).  The series is based on the same origin as the Heroes of Might and Magic games (Kings Bounty, back in the 1980s), except the King's Bounty games are truly excellent. I've always felt that not only was the best HoMM game Heroes of Might and Magic 2, but that the later versions were boring or even painful to play.

Hmm.  This may not be what you're looking for: Kings Bounty is more of an RPG with tactical battles.  They're still excellent games, though

looked into that diminion 3.the gameplay  may be deep but 60 bucks for a 4 year old game that looks like it came out in 94 seems a bit arrogant of the devs.
