Has anyone bought anything on it? Does it work ok? I'm after their flight sims (I owned F-16 and F-29 ages ago and never finished them because they were extremely difficult) and perhaps Delta Force 2. Oh yes and Tachyon The Fringe
Any experience with their games on modern systems?

It would be awesome of course if they distributed through gog but seeing as they have their own online store that seems doubtful :(

novalogic support is pretty good , i have the novalogic collection from steam and everything worked perfectly [most games require you to make a novalogic account on that site and activate the cd key] , i also noticed the multiplayer works good , community is still keeping it alive
the later delta force games are heavily drm'd , hence the absence on gog

Cool :) It completely slipped my mind to check whether there were steam releases. Seems like everything is there.
