Out of curiosity, what content are you looking for? Discovery on Lemmy can be a problem, but sometimes the communities are there and even active, just buried.
But may I also suggest searching by Top Day/12-hour/6-hour to see the most active posts. Lemmy’s scaled algorithm still doesn’t get it quite right IMO.
I really enjoyed my time with it, even though I’ve not played many games in this “style”.
The campaign is quite lengthy even though it’s not finished yet, so you’ll definitely get your money’s worth.
