a licensed conversion of Settlers 2 for Amiga 68K/PPC was being coded by Titan in 1998/99?
The story went that Titan had finished the Settlers 2 Engine (without any source code) and asked Blue Byte for the graphics and sounds when they informed Titan that they were not going to sign the license agreement.
The official line (in German) that Blue Byte gave for their actions was that they had doubts about Titan's ability to convert and/or provide ongoing support for an Amiga version of Settlers 2:
They didn't want their reputation and the legacy of one of their most successful game series compromised by a slack or inept 3rd party publisher. They stuck to their guns despite pleas and abuse in email from disappointed Amigans.
Below is the only game pic that I've ever come across from the Amiga conversion.
