Civ 2 was such an improvement over the first one. I remember both playing and baking mods for it after I exhausted the base game. My second favorite in the series.
I've settled firmly into the road-mountain hybrid groove so it's really just about having it be tall enough for me to fully extend my legs on the downstroke, and not have to hunch my back to grab the handlebars.
Though, druthers, it'd be electric lime green all over.
As a transmillenial student of AI / ML, great write-up.
