I've been intrigued by the idea of having only one victory condition but that still caters to different play styles. I think I came up with a novel new victory. My idea is to completely scrap the existing victories. Instead, the player would win by achieving any 2 of their choice of the following conditions: 1 - Control at least 75% of all land tiles. 2 - Research 5(?) future techs. 3 - Research 5(?) future civics. 4 - Achieve 1000(?) tourism. 5 - Have your religion be the majority religion in at least 75% of all cities. 6 - Reach a total population of 400(?). 7 - Build at least 20(?) wonders. 8 - Recruit at least 20(?) Great People. 9 - Ally with at least 75% of the civs in the game. Some of the numbers that have "?" around them could be tweaked to make sure the choices are adequately difficult. But you get the idea. I purposely picked 9 choices that cater to different areas of the game. As you can see there is something for every play style. But at the same time, all the choices represent something great about your civilization. So, this victory would still represent the idea well that your civilization has achieved true greatness. It would also help cut the game short maybe and avoid the late game malaise since when a civ has achieved 2 of these choices, they would be pretty dominant anyway and deserve to win. This new victory would also allow players to customize how they win the game. With needing any 2 out of 9, there would be a lot of permutations, giving players lots of different ways to win. I calculate that there would be 72 different permutations. So this idea would give players a lot more ways to win the game than the current static victory conditions.
