1. How many chapters of this mod are you planning?
2. When you release all chapters, will you merge them as one complete adventure?
At this stage it's looking like it will be broken into 3 chapters. So as a
general overview, you'll be traveling from northern Egypt (1st chapter regions) down through the Nile valley (2nd chapter regions) to eventually reaching the great city of Thebes and onwards to Hamunaptra itself (3rd chapter regions).
Looking at that it sounds similar to TQ's act 2 progression, but trust me, it isn't haha. You'll be diverted from location to location through many branching paths, sometimes only advancing through underground passages and even crossing over the Nile in order to progress. Think of GD and how the regions have open areas to explore with branching paths and 'bottleneck' progression points
Also, you're visiting new places (or in some cases re-imagined places
) along the way, so for example the Necropolis of Sakkara; Abydos and the Jungle and Oasis of Ahm Shere.
Regarding merging chapters, this will be seamless - pretty much the same as the good ol'
'John Bourbon System' where you will come to a gateway/point to which you can't progress ...yet. Then, once the new chapter is ready you can DL the new content/build, load it up and continue from that point
Also, I've got some 'DLC' areas and challenge tombs planned as well
