getitgetitgetit! If you like isometric turn-based games with rich setting, get it and play it. It has a rich and original setting, unique themes and gameplay. I'm not hyping this cause I have anything to gain, I'm hyping it cause it's a damn good game made by an independent producer. Usually I steal these games and buy them after (heh, same as Arcanum,) but I've pre-ordered Geneforge 5. If you love Arcanum and original Fallout, you'll enjoy this series.
Here you go, lazy bitch...http://www.spiderwebsoftware.com/products.html Avernum listed there is also good, mostly. The first three, very good, the last ones, very unnecessary. Nethergate I never got into, but it's a decent historical fiction/fantasy based on Roman occupation of ancient Wales.
