I started playing Pokemon Sun again. I'm only up to route two though since I haven't been playing much.
Spent at least a half hour training Luffy my mankey on route two before I found a Smeargle and it ended up struggling itself to death. Stupid thing.
So I spent another half hour looking for another one until I found it and caught it.
If I'm ever bored enough, I might look for shinies in Moon but I probably never will. Sounds like too much work.
I'd rather just look for rare pokemon I haven't caught yet.
