Yes, does not affect gameplay. The sandman mod is the one that will affect gameplay since you cannot see the sandman vuk with that mod, and it affects your view of the light show for Sandman.

I recommend the buildings and subway but not the sandman mod.

I had some trouble at first. I finally ended up removing the building closest to the flippers in order to give me a little more time to see the ball coming. That worked out great. It didn't have a big impact on the visual effect of the buildings.

Personally, I wish the mods were a bit smaller.

I love the buildings but am not a fan of either the subway or sand man mods. No offense to any that like those just my opinion. The buildings do not affect gameplay you can see the ball from the windows and can still track it. At first I wasn't sure if I would like them but after getting them I really love how they add to the look of the pin.
