nijuu: Who hasnt got most of Paradoxes games?. they are all perpetually one sale somewhere... sometime...
timppu: Mobygames lists like 136 or so games for them, not sure if there are even more by different "Paradox" names.
Anyways, I think the only Paradox game I have is Cities in Motion, and only because GamersGate offered it as a freebie at some point.
I have none of the other games, possibly because they are so GamersGate/Steam reliant, but also I guess I'd find all the grand strategy games too overwhelming, and possibly boring. But if HB offers them for a buck or two, maybe I will get them.
I wouldn't say they are steam reliant. From what I've read, even EU4 can be run without steam running. I do think most of the newer titles require steam to download though. I have a DRM free copy of CK1 Complete on Amazon though, so it I'd possible to find DRM free copies of the older titles.
I just this year tried my first Paradox grand strategy. I'm hooked, I wish they would steer clear of steam only but it seems they're headed the other direction.
