I like any sort of rpg that requires you to understand the text so you know what you need doing. Diablo 2 was my way to learning another language, but it’s fairly old now. Maybe something along those lines or that has a good crafting system? I would suggest stuff like Grounded, some of the Elder Scrolls (oblivion just got a remake so that might be nice), project zomboid, etc.

Haven’t heard a single speaker other than for a tour guide and those are clipped to their belts and connected via a cable to a mic.

I’ve been to a few of them, they’re pretty excellent. At least the ones I’ve been to had good signal and wifi throughout the park. Also a ton of staff to help.

Edit: I guess I’ve been to the national parks that are not IUCN certified like some of the historic mountains. Still awesome parks.
