So what you're saying is that you'd rather pretend that Pokemon hasn't seen a decline than live in the real world? Comparing just the Gen IV and V numbers to the Gen VI numbers there is a clear decline, just like with the games. It's not super massive, but it's there and there is no need to pretend that it doesn't exist.
Yes
I just don't see why it had to be brought up.
However, aside from the first two movies, everything has been level in the finals. Lowest being Pokémon Heroes at 2,607,000,000, highest being Darkrai at 5,000,000,000. It fluctuates between 3,000,000 and 5,000,000 otherwise
