SG was planned to be 3 seasons of 10 episodes each.
Recently Ocean lowered the number of episodes per season to 5, for a total of 6 seasons but the total number of chapters haven't changed.
The change in the way Summers Gone is organized came about due to Ocean's decision to do a Steam release. All the CH 1 & 2 rework (plus the continuity rework in CHs 3 & 3.5 and the music removal) is in support of creating a Summers Gone season 1 that is a highly polished AVN and quite ready for Steam (and now GOG) release.
I think it is a great call by Ocean and will introduce SG to a Huge Steam audience where it will be very well received.
I know I will be gifting it to a number of friends who have no interest in/knowledge of F95 but who would Love a great story like SG.
On Steam, Summers Gone will be able to shine as an Adult story with adult relationships.
There are many adults who will embrace SG and enjoy Ocean's storytelling and the way he does both world-building and relationship-building.
Think about the other special treats that Ocean will be adding to SG: the phone as well as Nami's Photo Book.
Those are going to be Great adds to an already rich and entertaining story.
I also appreciate how Ocean keeps us up to date on progress with his dev-logs.
There are too many developers who don't bother to give timely updates to their supporters on Patreon and SS, let alone periodic visits and updates to those who only come to F95 for SG.
We have a few months to go before we will get the CH 5 Beta but those dev logs and the 'who wore it better' contest he is having his Patreon and SS supporters vote on will help to keep me fully invested in SG while waiting for the next release.
