So, I found this game called Lost Technology a few days ago, and it had an interesting concept so I thought it was worth the cheap $3 price.
It's a turn based set-up, with factions taking turns on a world map to build up force, perform diplomacy, and attack, with battles being a rts system.
But the real kick is that is has a fair amount of story elements. While it is, sadly, right now a work in progress, the story and characters still go a step beyond the basics. There is a fair bit in there, but there's also a noticable lack of story as you get further in. Since I don't know how much work is left, outside of the number of factions that don't have any story implimented outside of pieces of lore attached to their characters (which is still a fair bit), I can't say if I would give it a full recommendation, but it's an interesting concept and might be worth checking out for those interested.
