Great Old One
I love the characters of Dragonlance, they are like old friends you met time ago. But Krynn as RPG setting is too limited when your PCs aren't the heroes of the lance. And if the canon lore by WotC allows the multiverse or alternate timelines in the D&D worlds you can bet lots of crazy ideas created by the fandom, maybe even a webcomic with some touchs of supernatural romance (song dragons? Yes, they are real, but they are like a mixture of urban tribe, life style and bloodline).
And they are visually stunning.
The thing is that, beyond the War of the Lance, I don't find the world of Dragonlance that interesting. And honestly, the modules are, overall, really really bad. Sometimes, I dream of just keeping the storyline and rewriting all the modules in a much better way and running it with people only discovering the story and playing the awesome characters, but I don't think I'll ever be able to do that.
Birthright only needs the right strategy videogame.
I agree, today it's much better to have computer support to run all these numbers anyway. And the same with BECMI dominions, which I used to absolutely love.
