It’s such a massive game that playing it in short spans on the subway seems almost wrong. The Fugitive, who is the player character, returns to their home town only to find it up in flames. With your help, I think this could be up and running within a week. I wander around my town, a between-missions hub world, talking to various merchants. I know that at higher levels you get better items from Gold chests but there are limited details out there. If you want a simple RPG on the Switch that costs absolutely nothing, The Elder Scrolls: Blades fills that role, but if at all possible you should definitely save up and get Skyrim, it's just a much better game overall.
