Are you hogging all the Wonders (NW, WW, and DH's )? Especially the early ones That makes a Huge difference
Not my game but she's a bit behind actually.
She's now starting to be caught up and getting some but it's been a sensation in a lot of games that the average turn to tech is decreasing as the game goes and that's before this Medieval point she's at. It's getting too fast for her to keep up with construction at all and we've already adjusted the construction cost curve.
She's getting techs in 2-3 rnds on Epic/Emperor and I'm thinking the goal was to get techs a round or two slower than that (Avg target is 4 right?). The problem gradiates through time so that's the purpose of that modifier is to address the tech cost curve so that it does fairly well at meeting the tech generation curve.
It will help with the AI a bit but it's not really the goal of this particular adjustment so much as it is for the player's experience.
If the AI needs to be held back some, fine, but I'm not yet entirely convinced - I know they are doing exceedingly well on the super hard setting you're on. Not yet sure if that's just appropriate for the difficulty level.
I'd prefer to see Noble eventually become the normal game difficulty one wants to play thanks to the AI playing nearly as well as the player does. This is the point at which the AI isn't handicapped at all and should thus be exactly what even a good player will want to play at IF the AI can play with nearly the skill of a human.
The reason the AI is so far ahead right now on these games we've been seeing is because we removed some major points of stupidity for them and they've been thriving as a result. We MAY be able to get away with reducing the handicap values for them a bit but for the most part handicaps aren't not applied against the AI as much as it is applied against the player - not saying there's not a little of both depending on what kind of handicap we're talking about of course. I'm explaining this more for those who are reading - I know you know a lot on the subject and perhaps you can make a proposal as to what specifically you're thinking should be adjusted.
Thing is, on Emperor, also a very elite setting, again, Medieval era, she's starting to catch up and surpass them in research, so I think it might take a little more evaluation. She's using tech diffusion so that may have helped her catch up faster - no tech trading - no WFL.
Anyhow, Rax was already saying that the time table is being beaten a bit too easily so theoretically due to that alone, this should be an appropriate next step to take to try to balance things back out.
I'm sure you've noticed a gradual decrease in the turn times to reach a tech since the Prehistoric right? I mean, yes it's supposed to waver a bit as the tech cost steadily increases on a curve and the tech output varies a lot based on buildings, number of cities and so on, but if we're seeing an overall gradual reduction in how many turns it takes to earn a tech as the game goes on, this is the way to react to recalibrate things and we're still looking for zeroing in on these calibrations on a fine tuning level at this point.
If it ends up feeling too severe, let's discuss, but again, this is based on speculative prediction and we'll have to see if it is felt much and if it corrects appropriately.
