Titles say it all, trick like that worked with several games in a past in both directions (not without some disassembly), for example levels and basically entire tomb raider games from 1 to 5 could be backported (with some minor limitations), some people used to port PS2 and Xbox exclusive levels and content to pc versions of games that shared same engines.
So I suppose Drakan 2 has nothing really new, except for levels and story and can be backported to PC without problems, and it can be created as stand alone unofficial port or can be as well integrated into Drakan as continuation of main story (not replacement).
Also some improvements like new model for Rynn https://gamerinfo.net/game/drakan-the-a ... ots&pid=13
can help a lot (textures however looks better in PC version of Drakan 1) could help even Drakan 1 to look a little better.
So, anyone want to try that? I wish I could do that, but I have no time and no experience with riot engine editing, but I think this forum has enough of capable people with time to port Drakan 2 for PC after so many years.
Also some updates for Drakan could be take from updated Riot Engine in Lord of Rings and The suffering.
