Aside from all the other praise people are giving it (which I completely agree with) I have to say, the ability to pause during cutscenes and access the database or whatever they call it to read about the characters involved in the cutscene is truly revolutionary.
Yep I had alien blue back in the day and it was essentially what Apollo is today (not quite as fleshed out as Apollo though). When Reddit bought alien blue I was actually somewhat excited because it was a great app. But they completely destroyed and tarnished it. I’m sure the dev who sold it (or was hired by Reddit, I can’t remember) is sad about it.
