I loved Tropico 2! I don't think I've played any of them since Tropico 5 (which I think I last played, sometime last year). I haven't tried 6, but I'll look into it.
I've just started playing Void Bastards last night, not really knowing anything about the game at all and just being recommended it. I love it though - it plays like an old school fps (I get old school Doom vibes from it, even though it doesn't really look anything like Doom 3D - I think it's because of the flatness of the enemies) but with some really simplistic stealth mechanics. Ammo's a bit rare so it sort of promotes picking and choosing when you go in shooting & when you sneak around.
I think part of the fun of the game, for me, was not really knowing much about the game before jumping in. But it was recommended to me by someone who pretty much knew I would love the game after he played it for a bit... so maybe I should explain the game more.
But if you just want to go in fairly blind like I did, I wholly recommend it. I think it's a brilliant little game. The way they handle the player controlled character dying/respawning is also pretty fucking brilliant. It's a very cool game, it reminds me of a lot of different games from the past... but in a way that feels really fresh and original and the game itself, imo, is very unique.
