Green Man Gaming has an interesting offer running
(not available in Germany, Austria, Switzerland, Russia, and any other country where the games are regionally locked -- make sure to check before purchase!) :
Buy Any Rezzed Title And Get 5 Free Games The following 5 games are free (Steam keys) with purchase of any Rezzed title:
* Rooms: The Main Building
* Time Gentlemen Please! and Ben There Dan That! Special Edition Double Pack
* Rabbit Hole 3D
* Clickr
* pid
They are also running a 22% off coupon code: H3U5TZ-9726D1-JIPSHC
I know that Time Gentlemen... has been said to be DRM-free after being installed with the Steam client, and some of the others may be as well.
The cheapest way to get these is to purchase
Critical Mass for
$0.49, and
apply the 22% coupon code: H3U5TZ-9726D1-JIPSHC However, Critical Mass only activates using Playfire.
Personally, I picked up the
Introversion Pack for $3.85 after applying the 22% coupon code, which includes Darwinia, Multiwinia, Uplink: Hacker Elite, and DEFCON Steam keys (I believe all titles are actually DRM-Free after installing with the Steam client).
TLDR version, I got the following 9 (potentially) DRM-free games for $3.85: * Rooms: The Main Building
* Time Gentlemen Please! and Ben There Dan That! Special Edition Double Pack
* Rabbit Hole 3D
* Clickr
* pid
* Darwinia
* Multiwinia
* Uplink: Hacker Elite
* DEFCON
I can try testing the DRM-freeness of these a little later tonight, though I don't know how long the deal is good for.
