Take this with a grain of salt but
IMHO,
evaluating wonders on deity fractal/pangaea/shuffle with TT on is pretty pointless, there's only a very tiny handful of wonders that are even worth considering building, under very specific circumstances. The rest are better as just failgold because the pace of the game flies by and the AI get wonders ridiculously fast with all their cheats
Despite being a deity player myself, my tier list is more targetted at immortal (should state in the video its a general average for anyone playing on emperor to deity), but in the tier list I made some clarifications on which would be a lot better on imm vs deity as I went through the wonders.
Stuff like mausoleum, hanging gardens, etc etc is much more realistic to get on the immortal difficulty because you can get it later and sacrifice a lot less to get the tech at an appropriate date. I.e. flick in currency before calendar.
I don't think we should be assessing wonders for deity difficulty also because a very small minority actually play deity, they just have loud voices and post here everyday, I think majority of players float between monarch to immortal, with a few casually chilling at noble/prince and a few playing deity.
That being said, I stand by my point that mausoleum is strong even on deity, as is great library, and the wall; ok, oracle maybe not so much- 1 tier down But there's a clear distinction between these and say crap like chicken pizza, angkor wat, zeus, etc. Plenty of deity games I have had reasonably strong positions I can just trade a tech or two for calendar to improve some resources, and then have access to marble so why the heck not build it. Then you pair the mausoleum with a taj golden age and you can just go straight to cavalry and wipe everyone off the planet that way, OR, cuirassier rush with all those production boosts.
I can't be bothered getting into an in depth arguement about forges and buildings in the game, I play differently and enjoy and feel value from early production and happiness boosts to build momentum earlier, and enjoy trebuchet knight stomping targets on deity or immortal with the forge bonus. Making trebs/knights consistently whippable for 2 population instead of 3 population feels very strong and convenient to me IMO. that's 2 less sizes you have to grow. Same for cuirassiers, put a couple hammers into a cuirs then you can 2 pop whip it with a forge. It may have a touch of roleplay feelsgoods in building more buildings? I like flicking in harbors if I have GLH or overseas routes and planning to play the late game, idk, seems a very small investment for fast payoff in commerce per turn plus prepares for lategame factory unhealthiness. Might slap a market into the capital (AFTER bureaucracy) if the capital feels worthy and has nothing better to do. The gold is nice and doesn't take terribly long to pay off while the happiness can be real clutch if war weariness or defy anger gets annoying.
Maybe my play style is not optimal? but heck, I'd burn out if I only built 3 wonders ever and ignored 95% of the buildings and just spammed wealth in every city all game. Adding more elements and mixing things up and getting play out of wonders and niche strategies is how I roll and enjoy the game, and still find ways to improve as a player. Just FYI I dont mean any disrespect to any of you and a lot of people in here are probably better at the game than me, but, I do what I can to have fun and still play at a comfortable level. Its why every so often I drop the difficulty down to immortal even though I CAN beat deity so I can play a more flexible game and attempt harder maps.
