Bigs: Pretty crappy 2nd week additions... Humble I am disappoint!
muntdefems: As many other things in life, depends on who you ask. For starters,
Expand is a nifty (albeit a little too short) ability game. And then, the
Hexcells are the greatest pure puzzle games to come out in recent years.
(The solitaire game I don't know about, and I'm unable to try it as it's giving me a segfault in the only shitty old laptop I've got available at the moment. :P)
I was thinking the same thing. Two hardcore puzzle games and a softcore puzzle game? WTF? I trolled around on that other forum and found out that the Regency Solitare was programmed by a fellow that made a game for BigFish (as a contractor) called Fairway Solitaire. (According to dev) that same engine with a different theme was released later as Faerie Solitaire. I think it was even given away for free at one point.
Anyway, the dev said that Regency should be fairly similar to Faerie, so if you (and/or your SO) like(s) the one, you'll probably like the other.
While not available directly from Steam, there is a Linux version available DRM free from Humble.
