imo it gets boring fast because you just see the same pokemon over and over again. very very rarely do i see something thats not one of the 10 really common ones in this area, or get something from an egg. 99% of pokemon i see around london are, pidgey, spearow, rattata, staryu, drowzee, poliwag, slowpoke and goldeen, aside from those few i occasionaly see a golduck or slowbro. thats it aside from extremely rare occasions. if there was more variety in the pokemon that spawned i would probably play it more. even walking around for an hour using incense, i just get nothing.
