I do not have much time so this will be quick (Also most people don´t believe this)

Remakes of 4 gen are style Lets Go
Names: Pokemon Lets Go Riolu Pokemon Lets Go Buneary
Similar to Lets Go you don´t play as Diamond or Platinum but as two new character: Beryl (boy) Gemma (Girl)
No Megas
Many new gigantamax form
All (and just) Pokemon from 1-4 gen
Surprisingly , for me at least, some regional forms
Also surprisingly for me like in B2W2 you start in another town in Battle Zone
This is all
