thats so bogus if europe can use all but japanese why cant the rest of the world? unfair imo beach would be so cheap if this was possible here
Whether it's fair or not is up for debate; however, there is a reason for it. In the UK, language is a bit (i.e., a lot) more diverse than it is in the United States, and you're just a short flight away from several different languages. In the United States, your overwhelmingly dominant language is English, and you're very unlikely to encounter anything but English, with
maybe a side of Spanish. That's the reason why the zones are structured as they are.
I don't feel like making a fairness argument will get us anywhere - Europe may have best 2/3 swiss and free range on card languages, while we have all those neat things Ace mentioned. Regardless, it doesn't really seem that great to have the entire United States market locked to just a single language, whereas the rest of the non-Japanese world can use a mix of languages. It actually skews the metagame here, IMO.
The number one reason for this is that, despite Spanish/French being rare in daily use, they
are commonly taught languages here, so at any given tournament, someone probably knows at least one of them really well (possibly fluently). Even if they don't, then you usually have at least half a dozen human versions of Pokepedia.net .
Is it really that much of a stretch to consider English, Spanish, and French all usable for the entirety of North America? If that's the case, then is it that much of a stretch to consider them usable for Masters only?
