Also, if ORAS Megas are in the game, Hoenn starters are off the table unless they wanted to include all three, as are Kanto starters. Sinnoh might feel a bit recent given you could find them in the wild in the previous legends title, and Kalos starters will likely be found in the wild. So the only real options were some combination of Chikorita, Totodile, Snivy, Tepig, Litten, Popplio, and the Galar starters (And perhaps the Sinnoh starters if they didn’t mind them getting the legends starter treatment after appearing in a Legends game).
If we get another legends game, does this mean the options narrow down to Snivy, Litten, Popplio, the Galar starters and the Paldea starters? Or could Kanto, Hoenn, Sinnoh and/or Kalos starters be back on the table? (Imagine Snivy, Litten and Popplio being the starters for a legends game.)
