Over several iterations the Spirit Island app became good enough. However, as much as I love the game, it is immensely difficult to play in digital. Even when on my large monitor, I cannot show everything at the same time and I need to switch between maps and cards and I find it makes for much added difficulty. I have stopped playing the digital version. I have not played Scythe enough to be able to say anything about that app.
there were some really decent TTS mods when I Last used TTS. in any case I highly recommend finding someone to teach you the game if you don’t know it already. I have more than once encountered people saying they didn’t enjoy the game only to change tune after getting a teacher. It is not even that the rulebooks are bad. It is just a lot of moving parts.
