I haven't played any games seriously since White, but I plan on getting back into the series when the next generation/iteration switch games come out and dexit is over

I have the following options available to me from my gf___, what order does /vp/ recommend so I don't blow my brains out from reverse quality-of-life changes?

>DS games on flash cart
>Black 2 cart
>Soul Silver cart + pokewalker
>hacked 3DS for 3DS games and crystal VC
>Omega Ruby cart
>Ultra Sun cart
