Nobody has mentioned Blue Isle Studios yet. I played Valley, which is a single player, story/mystery driven game played in a wilderness setting with some cool movement mechanics. I can certainly recommend it if that sounds interesting to you. Their newer games are horror (slender man) or multiplayer pvp games that don’t get great reviews and aren’t my jam so I haven’t tried them but Valley was great.
Everything around them is built for cars. When that’s the case, and you have no car (are underage to drive) you essentially have no freedom because you can’t go anywhere or do anything. Bikes are great, they are also exhausting and impractical to cover the distances that cars can. An e-scooter can get you there faster than a bike and without being exhausted. I think it gives these kids a taste of freedom and independence that they crave.
