Trying to get back and finish up somy Skylanders Giants before moving on to Swap Force, but it has this really random issue of not starting up properly (playing the Wii version on a Wii U) and I haven't found a single topic that addresses the specific issue I'm having (because once the game does start up, it runs absolutely fine).
In the meantime, though, looks like I seriously need to give the console a system update (3.0.x to 4.0.2) . Hoping this alleviates the issue because the July (3.1) update specifically used the words "software compatibility" in its details.
