TheGrand547: Never heard of this platform, is it legit? There are a lot of games on there from 1C which steam versions aren't drm-free from my limited testing, seems odd they'd be selling them externally drm-free.
Well, before I bought any games there I wanted to make sure they were legit, so I searched high and low on the web and what I found convinced me enough that they are. Alas I did not think I would need to provide links to others so did not keep a record. There was also a bit of logic involved in my evaluation too.
They have been around quite a while, and while they may look a bit like an Abandonware site, they have very selected and limited slim pickings if so ... not usual for that type of site. I also used PayPal, and they will often blacklist illegal sites. I also found nothing that said they were illegal, and they get a mention (not separately) on Wikipedia and places like 3D Realms etc.
Hell, you could use logic to look at the fact they have very little Duke stuff there, and they don't just have the original.
I've bought several games from them now, and no way in Hell I would have paid if they were the least bit illegal seeming.
