There is discussion and hopefully false information on Steam about Amiga conversion being without permission:

If Hyperion wants to release any Gorky 17 title, they need to have an agreement with TopWare Interactive AG (because we own the trademark and all rights to the game title - this is easy to find out at OAMI patent office, patent runs until 2019 and will be extended to 2029). But however, we will try to talk with them. Not all disputes need to end up in a court case. Sometimes there are other solutions.
Let the games begin...
35 euro for pre order or 50 euro for main release.... or $6.00 NZD on Steam. Hmmm.
Oh "at a heavily discounted fair-price of 50,- Euro incl. VAT*) in contrary to the regular price of about 65,- Euro incl. VAT."
Heavily means 15 euros? LOL
