Like 90% of all games released within the last 8 years.
Honestly, I havent played pokemon since Silver and Gold ( I did emulate Leaf Green and Fire Red for PokeMMO, Where you see other players, trade pokemon/items and can battle them or join the massive PVP battles for control of MewTwo ) But i heard Diamond and Pearl was the last good game they released.
I think Gamefreak is in their experimental phase right now, which is dumb because they have a proven formula, they just don’t want to produce it.
