I got my start as a Pokemon Trainer with Yellow but not sure I could go back and play first gen again though.
Hopefully they've removed the "There is already a save file. Are you sure you want to overwrite?" prompt.
The game has far too many prompts. Even in the latest games, I wish there was a way to turn off the confirmation prompts for "Do you want to give a nickname for the Pokemon you just caught" (no I never do!) and the "Are you sure you want to give up learning X move" prompts" (Yes I'm sure I don't want that move).
