G-Doc: Hi,
I hate to be the herald of bad news again, but the legal problems with Guilty Gear games for the PC not only persist, but escalated. Jus as with GG Reload X2 earlier, per request from Fun Box, we are sadly forced to remove Guilty Gear Isuka from active sales as of today, 4:00PM GMT.
Hopefully, we'll be able to re-introduce Guilty Gear X2 Reload and Guilty Gear Isuka to GOG.com catalog as soon, as the legal issues with the series are resolved.
If you have purchased the games earlier, you'll still be able to download the files off your virtual shelf.
Again, we're very sorry for the inconvenience this may have caused you.
This is why I prefer DRM-free software. I already copied Guilty Gear X2 #Reload and Guilty Gear Isuka unto my external hard-drive years ago. Just in the event they get yanked. I do this with ALL of my DRM-free games and MP3s. I suggest others do the same.
There's no point in supporting DRM-free if users aren't going to exercise the option of making back up copies.
