If you could re-release a classic game now, but with additions what would you do?

For me I would re-release Age of Mythology. I loved that game and I have played hundreds of hours at my mate's house. I would re-release it with slightly better graphics but instead of the base religions (Greek, Egyptian, Norse) and the Titans expansion (Atlantean) I would add in Mesopotamian with a 3 of their gods like Ur and Uruk or something. I would also add the Incas. These religion's temples would be ziggurats, they would have large armies and their main units would be spearmen. I would give the Incas a mythical unit like a large panther that can travel quickly and stealth. That is my two cents, tell me if you loved a game and if you would add something to it.
