You have 82 hours (by my count) to click this link, and then pay what you want for Spiderweb Software’s Geneforge Saga. It retails on the developer’s website for $45, so let that be a guide to how much to spend. You can also optionally get the game added to your Steam and/or Gog.com accounts.
The Geneforge Saga is a series of old-school RPGs with a steampunk vibe, featuring turn-based combat. Of interest: the first installment debuted on the Mac in 2001, a few months prior to the Windows version.
Trailer below so you can get a better idea of what it’s all about.
