Lots of other great games helped me build my English skills, most of all The Legacy of Kain series.
I remember Final Fantasy 1 on gameboy had a surprisingly open world and I could walk all over the map, and it had random monster encounters. I'd be fighting a lengthy turn based battle about every 20 steps, and it could be way above my level, and I was completely and utterly lost!
I spent so much time on that game. But I never progressed far into the quest. Playing it as an adult I realized one random NPC says there's a hidden cave to the east, and if you never read it's pretty much impossible to find.
Similarly in Pokemon, bumbling through caves in the dark until I go out the other side through sheer luck and grit. Turns out the move Flash just lights up the cave.
