I've just discovered Square Enix are no longer selling some of their older titles (Such as the pre 2013 tomb raiders) DRM free. Having already owned everything up to AoD on GoG I purchased Anniversary, Legend and Underworld via the Square Store.

To make matters worse, they've removed the ability to re-download installers, for customers that have already bought these games.

I'm not 100% sure I have my original DRM installers, and right now I'm fuming.

I checked my email, there was no warning this was going to happen.

Have sent SE an email. Will update when they reply.
