I want more grass. It doesn't have to be even... Why are there so many patches of turf in the game? The grass isn't maintained, it should be tall and wild! The patches of grass are annoying. I want grass EVERYWHERE!
If your grass slider is pushed all the way to the left, you get very little grass surrounding you. Right displays the opposite. But going too far right causes game lag so I wouldn't recommend it.
Personally, I think they got the grass levels just right in most places. A few patchy areas sure, but not enough to really complain about imo.
