I tested Evan Chelio's sliders before (which are also called zero theory...), but I guess these are different. Anyway, I played with Truegamer's sliders and basically it seemed to work until late 3rd quarter when I again started to suffer from the fact that CPU scored e.g. an F 3pts and other low rated shots while I was missing some A/B shots from midrange. CPU also blocked like crazy almost everything I tried under the basket, while I was only getting fouls called against me. As before, offensive rebounds played into CPU's hand and my awful 57% FT (the worst I've had so far) looked quite poor compared to CPU's 91%. I think up to now, CPU always had >90% FT in all my games!?
I think these sliders are worth a closer look, but I will probably not touch this game anymore until the patch is out. I don't know whether I should expect anything from this patch, but if nothing changes significantly I will stop wasting my time with this game. Anyway, thanks for all the good suggestions here.
