Play:
Emerald(GBA)
Platinum(Diamond was the beta)
Black/White and it's sequel, Black/White 2
Fire up Dolphin and also give Colosseum/GoD a try. If you want, you can also re-play Silver with Heartgold/Soul Silver, a remake/ultimate johto experience in the same engine as Diamond
Don't bother with 3ds games, they're trash. Same with lesser/dual versions like ruby/sapphire or diamond/pearl, they're literally just paid betas
