Quoted from o-din:
The same guy has a Skyline, it is in decent shape, but he wants good money for it. With two inch flippers and the grand canyon for outlanes, it does look pretty tempting.
Skyline doesn't have the legs that other games from this era have. But it is one of the best looking games out there.
The center wheel where you can get any of the numbers overcompensates the difficulty you want to keep it a balanced game.
I'm sure you can adjust it to be more challenging. But if you are looking for challenging there are more challenging games out there.
