In C22, I had messed with all sorts of sliders to try and create decent/balanced games for T20, ODI and Test/FC all separate. In the end I found that the best balance was actually by using default (hard/hardest) for all player-controlled stuff, but fiddling with the AI sliders, and physics a teeny-tiny bit, actually seemed to give the best results. I feel like there was already some kind of built in trigger between the different formats, as with the identical controller difficulty sliders (Batting Hardest, Bowling Hard for all formats), test batting was legitimately harder, T20 was much easier to hit boundaries, and ODI was somewhere in between (ODI probably the easiest format as AI could never decide whether to score at 10s or .8s). I definitely noticed differences in the AI bowling "fields" (wouldn't call them plans exactly), and AI batting aggression. In T20s they would charge and loft often, making spinners both likely to get lotsa wickets, but also get pumped, in Tests I don't recall ever seeing a charge, and in ODIs only some batsmen would do it. (Admittedly I had different AI run rate slider for each format), I don't think that was down to mentalities, as they never worked anyways, so it felt like the AI recognised the different formats, and would play accordingly.
Is there this kind of feel in C24? Does there appear to be a difference between formats, without changing too much off the settings?
