There's another issue here.
Tradition is always going to be the safe bet doing anything in this game. It's really hard to mess it up, honestly. People all over this forum advocate doing everything with Tradition because it's almost impossible to fail. I personally have never, not once done a tradition turtle to XCom domination. Nor have I ever built a stealth bomber for anything other than novelty. And yet, if you look around the internet you will find that exact strategy being touted as a "domination victory."
I completely disagree. While it's technically a domination victory and gets you the pop up at the end of the game that says so, it's anything but. It's like calling the same thing a culture victory, while true, it's disingenuous to speak about the victory in those terms. You're not doing anything different than a normal science/diplo game except altering the tech path slightly and finishing around the same time.
Furthermore, if we accept the claim that many people make, if you're any good at the game at all it's impossible to lose even on deity, then we must then make the claim that a tradition win, no matter the method or timeframe is pointless. You could win it with your eyes closed just by spamming Xcoms and stealth bombers right? Right, so then it becomes nothing more than a fallback for bad play, and a safe bet.
For a lot of people with many, many hours into the game (such as myself, and Carl up here), this is an unacceptable way to play the game anymore. I know I'm going to win every game I start, the only question is how much effort I'm going to put into it. The trouble is that people like us are underrepresented on the board, and you can see why historically. The people that are bored with the game and switch to fast domination tended to master that and then quit posting. tommynt posted some unbelievable domination finish times, Ironfighter was around in the early days just kicking over tables and having his way with the game. Cromagnus posited you could clear a deity map in 100 turns with Attila and very nearly did it. Some other people, inspired by his words got pretty close as well. And just off the top of my head, Consentient turned into a pretty pro player who did a great service for everyone reading this thread and put together a ranking of civs to use if you plan on NOT turtling your way to a boring victory. Peddroelm proved HCA is not only viable, but extremely effective.
What's the common theme of the above? None of them post here frequently anymore. By and large, people thinking outside of the box and forcing new strategies are done posting here. Thankfully, their posts still exist so that people can learn from it, but the echo chamber that is the "tradition turtle your way to victory" is just loud and obnoxious. If you've been posting here for any amount of time you can see that there are many better ways to do things that have cropped up over the years, they just don't have vocal proponents anymore. And I don't have a dog in the fight, since I wasn't part of the crew leading the charge on innovative strategies that challenged the established tradition > all crew, I just came in at the right time to learn from it.
So really it comes down to this - you can do things the safe, and boring way, and that's fine. It's still going to get you a W. I don't really care how you do it, but it's pretty disingenuous to say that nothing else works, or there's not a better way. Like hell there's not - I'd love to see your tradition empire clear a deity pangaea in 113 turns -

I really improved my game as a result of reading almost everything on these forums for years, and it really irks me when people try to downplay one strategy that's nearly impossible for a monkey to fail at as being the fastest and best way of doing things when there have been so many people who have proven it wrong, and just aren't around to show you how to do it anymore.
