The new Pokémon games are bloody fantastic, in my opinion the best since Gold/Silver. However, one of my personal favourite features is also one of the stupidest, silliest and easily-exploitable things in the game. I am, of course talking about the wonderful world of Wonder Trading.
For those who have yet to play it, Wonder Trade is when you put up a Pokémon up for trade and the game will find a random trainer to trade with you. You don't know what you're going to get until you get it. You can probably already see why this would potentially be terrible - there is nothing to stop people from putting in their level 2 scrubs in the hopes of getting something awesome. Most of the time they will get...a level 2 scrub right back (though I've found that I actually get a fairly small amount of low level Bunnelby's and the like).
Wonder Trade can, however, be exploited very easily - there's no limit on how much you can Wonder Trade and this means that if you get something you already have? You can immediately trade it away again in the hopes of something new. If you are patient enough, you will get something decent - or at the very least, something new you've not got yet. It's perfect for collectionists such as myself - but if you're looking for good, strong Pokémon, then perhaps it's not for you (saying that, I've got a few that were around level 50, so it can happen). Chances are you will end up with a fair amount of just hatched out of the egg, level 1 Pokémon, but even these can be beautiful sometimes - I've had a level 1 Bulbasaur and two Charmanders - the second of which I traded for a Froakie - but this isn't really a problem with the Exp Share, you can easily level up your critters without needing to stick them into battle.
The point is, Wonder Trade is a wonderful tool if you want to fill out your Pokédex. If you dislike the randomness of it all, there's always the GTS or even your own friend. It even gives you an insane amount of Poké Miles, which you can use to buy items from a man in the Poké Centre in South Lumiose City - which basically means it's a way to get almost unlimited Ultra Balls and certain other items. It breaks the game if used to it's fullest potential - and that's why I love it! Because it's completely ridiculous in every way possible, yet it's completely optional. It does, however, take away the satisfaction of catching your own Pokémon, especially if you get something from an area beyond where you are. Thus I'm going to stop myself from using it until the end-game and I'm ready to complete my Pokédex. So yeah, Wonder Trading is a completely broken thing, but with enough patience it can be YOUR completely broken thing.
It's also weirdly funny to send random people Slowpoke's with supremely Scottish names. I wonder how Hamish is doing in Japan?
