JustAdventure Shop Experience:
I just purchased Black Mirror 1 from them, for $2.49 was worth the experiment.
I also had trouble with setting up my account, but the support reply was helpful and nice within 12hours (usual time zone issue, you cannot expect people to answer at 4am ;) )
what I find awkward that they don't email the serial to you,if one is needed
or the d/l link.
you only seem to have access to these infos on the payment confirmation page!
The download is linked on fastspring, so you should be able to redownload it
it later, given you still have that link.
D/L speed is 900k/s here.
As a first resume, you better make a safe backup of your Serial# and download and the payment confirmation page!!!
Don't know yet if this will entice me to buy more from them in the future, but at least they do't use any wonky DRM, at least in this case and they seem to have some pretty good deals fro time to time.
Also since they exist since 1997, they must be doing something right.
I've been a member for Justadventure for a long time on their forums. It was mainly a great adventure-game focused site for reviews and talking on the forums. The shop came later on and while it can have some problems from time to time support will usually get it sorted out quickly, at least in my experience.
A bit of sad news is that the sites Founder , and former owner of JA (he sold the site a while back,, Randy Sluganski, recently passed away last month :(. He had been battling cancer for quite some time and still tried to keep up with the site as it was his passion.
If you like adventure games you should register there and post on the forums, there's a few of us that are here on gog as well from there.
