GOG.com is having a special event for owners of either the first or second Witcher game. All you have to do is to have bought the game(s) at a retail store at some point, and you'll be eligible to snag a digital copy of either one (or again- both) totally free of charge- and DRM free of course.
Aside from the online backup copy of your Witcher(s) that you can access at any time through GOG, you'll also get "tons of extra (ed- digital) content like wallpapers, videos, artbooks, and more". All of that is free too.
To get yours, head to www.gog.com/witcherbackup and add your product key. If you have a GOG account, the game will then be automatically added to your 'shelf'. If you don't have one, it only take a few minutes to sign up and it's well worth it- even if for nothing else than just the digital copies of the Witcher titles.
What if you bought the games but don't have the keys anymore? You can still participate by filling out the manual verification forms. Actually, that's maybe the best part of the deal, if you lost your key you can still get a copy and get back to playing. Not too shabby. Act fast though, if you want in on the promo you only have until June 30th.
Also worth noting is that the SRP of The Witcher 2: Assassins of Kings (in case you don't have the game at all) has dropped to $39.99 (USD) in the US and "much of the rest of the world". Oddly enough; the UK, EU, Australia, and New Zealand are exempt from the drop and still have to pay full price.
For its part, GOG promises that gamers in those countries will be able to take advantage of their "fair price package" and will get "fair value for their money no matter where they live". What's that mean? Although I'm not entirely sure, GOG does set its charges at US pricing levels no matter where in the world you happen to be shopping from. I'm guessing that if you buy from them, you'll get that $39.99 price wherever you might be- just check your total before you commit to anything.
