For me it's just a way to name game versions. I don't like the "0.15.2.b" type of naming game versionsmy comment was simply based on the "episode 1" part, not your progress nor content, or anything else.
I've just found too many games seem to split there game design in to several parts now, and way too many seem to charge prices for each episodes and splitting the "main game" in to like 10 parts / episodes now, and charging like $10 per episode.
so yes, any ways. it was just about the "episode" part nothing else.
So yeah, each new game version is a new episode. I think it's easier for perception for both me and the players. No extra charges
