I know the first edition is inconvenient.

There are many people who do not speak English well in my country.

So many people play games by attaching printed output to a board or card.

I can not put the output on the app, so I want to play mansions of madness, but I can not enjoy the second edition.

Is there no way to buy the first edition?

Find someone who owns the 1st Edition and is willing to sell it. On and off there are offers on Ebay and similar platforms. A store specializing in old and used games might have one copy for sale.

But I imagine it could take you a bit of hunting before you find one.
