I already suffer from tinnitus and would not wish to add to it with actual bells ringing in my ears.
In my youth I collected stamps. You bought the album but other people paid for the stamps to send to your address
so it was very cheap. Today collecting email address headers isn't quite the same.
Some people spend years and thousands of $$$ (or even more) building real miniature railroad layouts in their basements (if they have one and basements are rare here in Oz) or the garage (and what's wrong with parking the car out on the street anyway?). But I suppose I should not comment on that because I started my current Trainz Plus/TRS22 project back in the days of TRS2004 but it does stretch over 400km, much too big for any garage I know of.
But, when it comes to hobbies, it really is a case of "whatever rings your bell". Tony is correct, Trainz is a cheap hobby. Apart from just a few odd versions I have purchased almost every new release. I even have the latest Android version on my phone which I use to show disbelieving friends and relatives that you can run a railroad on your phone. It has given me endless enjoyment and I am more than happy to return the favour by supporting N3V.
My thoughts.
