I started out as a mountain biking kid with my dad, but pretty much exclusively road bike now. To be honest, I routinely go over grass and dirt on my road bike for shortcuts, as long as you’re careful it’s fine. Especially if you throw slightly more robust tires on them and it’s more the occasion than the rule I wouldn’t worry about it.

I’ve had good success either using steam (proton is basically seamless and mostly runs by itself in the background without me having to do anything), or lutris for non-steam games
