Yeah, Monocolor has never really been super popular, but there have been people like Chevitile and myself of course who were and are committed to doing all the colors through the first 5 gens at least. I'm on my last color, Purple, with only Hoenn, Sinnoh, and Unova left as of now, unless I decide to get a 3DS. Unfortunately, I don't know how I can justify buying one only for X/Y/ORAS, as I've never been much of a handheld gamer besides Pokémon, although the 3DS does have more capabilities than previous cartridge systems, and is way cheaper than console. I would probably use it enough just playing X/Y to finish monotypes and monocolors but it might get old really fast playing the same game over and over. Maybe when the next Kalos game comes out, if there is one?
Your task is to convince me why I should buy a 3DS besides for Pokemon, keeping in mind that I work full time and dont really want to become more antisocial than I already am.
