I was kind of on the fence with the first two phases of Eden. I loved the call backs to FF8, but Nomoura... is a struggle for me. So, I really appreciated the spin on community expectations, especially with regards to Griever and Ultimecia.
It was quite late, but I essentially got that because the First was so tipped towards Light from the get go, that what worked quite nicely for us in the Source when it came to undoing the likes of Nabriales, had the unintended consequence of creating Eden? It was about 12.30am when I got to the end...
Also, totally worth it for the end sequence replay of the FF8 ending. When I was young and buying games cost me weeks of saving, the only game I had for my PSX was FF8. I would reload the final save, enjoy smashing the last bosses and watching the ending, so I knew the beats of that cutscene very well, and it was great to see the gunblade / reunion / flower field in order
