I'm mostly an RTS fan. These are probably my all-time RTS games in terms of gameplay and replayability, in no particular order:
>Command & Conquer - Combined Arms>Company of Heroes with Blitzkrieg Mod + Historical add-on>Kohan: Ahriman's Gift>Rise of Nations: Thrones and Patriots/Extended EditionFor the DOS/early Windows era, I like Z, the first two WarCraft games, Castles II, and Dune II. Z and Castles II would probably feel the nicest to a modern audience, but I love the aesthetics of Dune II and the original WarCraft especially. People today might find them tedious, but I love the atmosphere and still revisit them every so often despite being more of a skirmish guy than a campaign guy. I like Command & Conquer and Red Alert for similar reasons, although I feel like the gameplay is superseded by games like Combined Arms. If you sent me back to the late '90s, I'd rather be playing Dark Reign. It didn't have the cool presentation of Command & Conquer, but it had things like unit queuing that made it feel less antiquated for skirmish and multiplayer play. I haven't played it in a long time, but I remember it being fun. Command & Conquer might be my favorite game series overall though.
If you can't tell from some of my choices, I helped contribute a few suggestions to that /vr/ DOS game list back in the day.Some other games deserve honorable mentions. Populous: The Beginning is unique and has some nice twists on the typical RTS formula. I've also always loved the way Stronghold: Crusader combined city-building mechanics with an RTS game. Warzone 2100 had some interesting features, like the modular unit types and auto repair command. And even if I prefer the presentation of Rise of Rome and find the second game more well implemented, Age of Empires III is probably my favorite Age of Empires game.
At some point I need to give the Celtic Kings games a try. I think they might be up my alley, since someone on an imageboard once told me that Kohan sounded like it to them.
For turn-based strategy games, I used to love Civilization IV but over time grew to hate the combat system and just find that aspect of it tedious now. My favorite turn-based strategy game is probably the fheroes2 version of Heroes of Might and Magic II. Heroes of Might and Magic III/VCMI is better balanced and has some nice additions, but I don't find the combat as fun or the aesthetic as pleasant. I would love it if there was a game that was basically Civilization IV but with the battle system of Heroes of Might and Magic.
The Advance Wars games were fun, but I don't find myself in situations where I feel like playing something like that.
I also have some GOG releases I bought but still need to try, like the first two Age of Wonders games, Alpha Centauri, and Master of Magic.
