Pokemon Omega Ruby
Pretty sure it will
No each Pokemon game has it owed save files. They will not moved from anywhere else but that copy of Pokemon.
On the store? I am sure the team members will not have an issue with you testing the game. Online you have 30 days warranty replacement.
Rest assured that we'll never sell illegitimate copies. GM - SMRT
Nope. 3DS and 2DS family only.
Most will just come with the game card, I highly doubt they will come with any original box/case/manual
depends on the person. Dome will earse their save file, while others won't. Hopefully you'll get luck and get pretty much every legendary in game wise. Just saying.
Yes, all versions of Pokémon listed in Pokémon bank are compatible (gen 5-7 games (the gen 3 remakes count as gen 6 too))
