What's your favourite game in the series and why?

Orginal Silver version is by far my favorite. I'm expecting HG to be amazing when I get it, just need work to start up. I absolutely HATED R/S/E, they were so dull and near impossible to get into until about the 7th gym.

Non mainstream game would definitely be Pokemon Snap. The whole concept of the game just made it so fun as a kid, and still does today.
