Pretty similar with regard to Offense, Defense & some attribute tweaks but there were a lot more sliders in 2K13 that I either left at default or only slightly tweaked.
With this game I guess because of the excitement of next gen and just how crazy real it looks, I've been a little more into the tweaking. Just more determined to "fix" anything that pulls you out of the immersion, because it just plays so beautifully with the right tweaks.
