>>53384784I did my regional dex over the lockdown and that was annoying enough, but I've been working on my national dex and I still to beat colosseum for Ho-oh. I have emerald, ruby, sapphire, fire red, leaf green, colosseum, XD:Gale of Darkness, 2 GBAs, a gamecube, and link cables. I'd say it's not worth it for the national dex, but getting the regional dex wasn't so bad.
>>53384798All of these unavailable in emerald can be found in XD:GoD except for Meditite/Medicham, so you'd still need at least three games to finish the regional dex.
