By deciding to deliver on the basis of the single scene, the dev proves that he is not at all trying to shorten the overall time that his game will last (between 20 and 25 years). Rather, he seeks to lure his supporters with updates closer to each other in order to keep them occupied.
But the big picture will be that the medium sized scenes that we have seen so far will be stretched to the maximum to constitute an update. And if he will start with an update every 3/5 weeks, as usual, he will put forward all kinds of pretexts to bring them down to 8 weeks and maybe more. And he thinks people are not going to complain because they will feel like they are playing AWAM every 2 months compared to 5/6 months in the past.
We will talk about this in a year, but be sure that the playable day will go from 1 year to over 18 months without the dev worrying.
We all remember the first promises of 1 playable day per month. And then he adopted the trick of the 1/3 of playable day per update system to speed up the pace and we all saw that it only slowed it down even more.
