Showing free demos as their own line item in the store suggestions feels counterintuitive. As a user, I don’t want this, it just clusters the interface. I want to see the main game and something on it indicating a demo is available.
As for developers, discoverability is something they are always talking (complaining) about. Artificially inflating the sheer number of competing games for visibility seems like an odd choice in that regard.
This isn’t limited to the Reddit app. You can see it on the desktop and mobile website too.
