There are a few "impossible tiles" like you mentioned, that's just bad luck. Or living in the mountains (not impossible but a lot harder) or next to a lot of water (start kayakking). So you need a bit of luck with where you are located, how much free time you have and how much money (trains, cars) you're willing to spend after your square gets too big to expand starting from your home.
In the end it's just a bit of fun but not an equal playing field for everyone. The main goal is to go explore places you haven't been before, some shit, some nice.
