Prison Architect was, the last time I played it, a fantastic game. It contains the satisfying construction and management of Theme Park and the dynamic, emergent behaviours of Dwarf Fortress. It also dealt with its heavy subject matter with appropriate but not suffocating seriousness. Is this praise still true after recent updates and DLCs? I’m not so sure, but I bet there remains a strong core. You can grab it for free from its Epic Games Store page. Godfall is a stranger beast. From the creators of the excellent discontinued card game Duelyst, it’s a co-op third-person action game with an aggressively gaudy aesthetic. Or as Alice B put it: Which sounds, honestly, pretty great. Alice liked the combat, too. What’s being offered for free is slightly complicated, however. Rather than Godfall as was released last year, this is Godfall Challenger Edition. It’s a cut-down version of the game which offers three endgame modes and a taste of high-level loot, but not the full game. This same edition caused a fuss last week when it was offered for free to PlayStation Plus subscribers, who normally receive free versions of whole games. Godfall’s developers denied that the Challenger Edition was a trial, saying that it a new limited-feature version that would normally cost £12/$15. In any case, if you grab it for free and like it, you can currently grab the full edition for a discounted price, also via Epic. Both Godfall Challenger Edition and Prison Architect are free to keep as long as you grab them anytime from now until December 16th.
