If you haven't heard, Nintendo will be shutting down the online aspects (all online gameplay) for Nintendo DS and Nintendo Wii Games on May 20, 2014. Even if you play these games on newer systems (3DS / Wii U) you still won't be able to access the online sever to these games.
I personally don't like this one bit. I'm a Pokemon Gamer, and this takes away a lot. I usually trade within my DS Games and then transfer them over to my 3DS (this is how I usually fulfill trade requests). With this shutdown, as far as Pokemon Games are concerned, you won't be able to access GTS, Online Battles, or Online Trades. This takes a lot away from those games, and a lot of people still play them (obviously not enough for Nintendo to keep the Online Server for them). This also takes away the chance to try to "catch-em-all". After the Main Story-line, now anyway, these Pokemon Games are pretty much useless.
So, what do you think? I know there are way more games that will be effected by the shutdown, but I really only play Pokemon. :p
