To anybody who will be claiming Last Wish when it inevitably goes free in a few days:

Due to how Amplitude structured the Last Wish package on Steam, you may run into a few difficulties with activation.

• If you do not own the soundtrack: Activation will go smoothly. You will receive the MP3-only version of the soundtrack. You will be barred from purchasing the full soundtrack in the future as the base soundtrack app has now been activated on your account and Steam Support will only be able to "help" you by removing the entire Last Wish package from your account.
• If you already own the soundtrack: There have been conflicting reports since release here. Some say activations go fine. Others say Steam refuses to allow purchase/activation because you already own part of the package.

I've already said my piece about how this all went down and my feelings about it, I won't repeat them; if you wish to know more, check my reviews on Steam. This is just a warning to new activations that there might be difficulties with your activation.

Thank you! I've remembered how Amplitude backstabbed me on this one, so now everyone will be affected too.
