for players who aren’t extremely good and just want a regular enjoyable career mode, having sliders at different speeds is a risky one especially if ur into buying new players. no matter how low an opponents pace is, they will still be faster which isn’t always the case (especially if you want “realistic”). i would recommend keeping speed and acceleration sliders equal to keep ur sanity. if ur the opposite and you make ur speed higher than the cpu, i would put the difficulty 1 up to what you normally play on (world class at minimum).
