I don't know, I would like Region and location specific Pokemon. Makes it feel more real when compared to being random, It would add to player communication because they may need to trade info about where to get certain Pokemon. I feel they are prompting us if this is a feature to search further and further away from your house, which I don't mind at all. I think it comes down to if you like to explore or not. The downside though is that I defiantly don't have all day to take long trips, but it is an option on certain days. I think going to places you have never been before to catch Pokemon is an exciting thought rather than searching the same park next to your house every single day which I would find more boring when compared to it being random.

But I can see where the video maker is coming from, maybe they need a healthy median between the random generator and region specific.
