i only choose to challenge people with 3 or more bars. however, about half the time i get either "game is full," which makes sense cuz somebody challenged before i did, or "unable to play." this message is more confusing but either way i can't connect at least half the time. what's also annoying is i hit X to search again and i end up with the same people over and over again.

>you'll come across better connections and they will start up
>with no problem.
