Query: You may need this, but you may not

(why is this listed as a "game"??) In any case, a previous reviewer is correct -- mostly -- about this gadget probably not being necessary.But there's a catch: Even if you have a wireless internet router, you may still need this, or something like it. That's because Nintendo DS is finicky about what routers it will talk to, such as the ActionTec router that came with our Verizon DSL. Check the device compatibility list carefully to see if your router, or one you intend to buy will actually work.Better yet, I suggest you look at getting a WIFI CONNECTOR ADAPTER USB FOR NINTENDO DS & SONY PSP instead, for around $40.Unlike the DS WiFi here, that one will also allow connections by laptops and other PC's, as well Nintendo and Sony. So what's not to like?
