I think it's a valid point, however I think it'd be a very small % of people that actually go out and buy a machine. A 99cent game is a big difference from a $2000+ machine. Haha, With that said though The game personally revitalized my love for pinball and on the path of purchasing. It wouldn't be an option though if I hadn't just bought a house and have lots of free space.
Sorry about that! Sucks for me too as these increasing prices are gonna make it harder.
