Thank you to everyone who participated. The number of responses is quite impressive!
I might be sharing the findings later on once I think I have received a good number of responses, but so far I'm seeing that almost half of the players like outdoor better and the other half is nearly neutral between indoor and outdoor.
So for those who doesn't prefer one over the other, what is the deciding factor? Weather? Or is it just undecided because you like to change up the environment and play style once in a while?
