Open world terrain tiles question: Hexagonal shaped tiles

The idea for the hexes is that they’re really large (65 Km² or something about) and supposed to be open world. When a new game is created they’re shuffled randomly
so one time a forest would be near meadows, another time it would be next a mountain or a desert, and orientated differently; without the control of the player or the developer
The player starting point would also be randomly generated.
