Oh wow I haven’t seen that Post yet, I was mostly going off of the new stats that they introduced in this post.
After reading the whole thing, and watching a part of the Grow Q&A, Engagement is supposedly the most influential factor when it comes to home recommendations.
To back this, my games Life Purpose, Madi’s Wardrobe, and My Judgement all once had close to, or more than 1 million home recommendations in their primes, their only viable statistic being their playtime since they were single player story games, you play them once and that’s it.
In the link you gave, they have this outline
Build → Pass Moderation → Grow Initial Audience → Get Assessed → Iterate → Get Rewarded.
Since I am already getting 40k ish home recommendations, I think I am already passed the “Get Assessed” stage, and I can definitely say that I have been iterating, since I brought the playtime up 5 minutes, including the increased Day 1 retention. So. Where is the reward??
