One of my absolute faves of any RPG style play, was Birthright: A Gorgons Alliance.
You could RP that game and go on D&D dungeon adventures to enhance the 3 ways of winning,
you could win the game economically thru merchants and trade
you could win the game thru political means
you could win the game thru military conquest
One of my absolute favorite lines of dialogue from any game, came from that one. During a dungeon excursion when you encountered orcs, 1 of them would inevitably say to you.. "c'mere. I'll make ya into a dead guy"
