A Question I haven't seen asked.

How many vehicles spawn out of one vehicle disk? For example, if I want Mickey's car, and my brother does, will one disk spawn one for each of us, or do I need two Mickey's Car disks? I ask, because I'm not looking to play unfairly with the Power Disks. Also, is it Disks, or Discs?

I think you will need two disks, because the toy goes with the disk, so only one would spawn. Not 100% sure though

Basically disc can be spelt either way but for Disney they are calling them Power Discs and not Power Disks.

Okay... I spelt it wrong so many times!

I have just realised there is two ways to spell disk/disc ha ha. So,etching I haven't noticed before

You will need 2 disc because if you put the disc on the base it will spawn that item in the toy box until you remove it from the base.

Looking forward to the trading forum?

Well, not nessicarily, they could always have the option to spawn vehicles without a disc- I don't think it will happen and I'm guessing you will need doubles, but there's a possibility, and I wouldn't say "definetly need two" just yet.
