platinum was fun, after i got heart gold and lost it, darkrai is still on that pokewatch thing that i forgot the name of
there's no need to change your mind it's 100% fact that platinum is the best main series pokemon game
There's so many better choices though. For example: Gold and Silver Crystal Ruby and Sapphire Emerald Heart Gold and Soul Silver Black and White Black 2 and White 2 Omega Ruby and Alpha Sapphire You can fight me, but I'll come swinging back.
Bruh 5 has so much post-game, great pokemon designs, and great story. 2 was basically two games in one 6, 7, and 8 are too handholdy for me to rank them higher
generations 1 and 2 are boomers gen 5 is the zoomers gens 3 and 4 are normal people and no one really cares that much about 6, 7, or 8
I haven't played any gen 5 Pokemon game as I fell outta love with the series for a while. That said - Emerald is by far what I consider the best main series Pokemon game with Pokemon xd gale of darkness being the best non-main series game.
