Avernum 4: Greed and Glory is akin to reading a good fantasy novel: it’s deeply engrossing at times, requiring a fair bit of imagination to bring the world to life, and likely not the most modern method of accessing such content. But in saying this, the subterranean stories of Avernum, and its many detailed factions and quests keep you moving forward and invested in what’s coming over the next hill cavern. The commitment to playing an open role and of exploring everything on your own terms and time is an element many modern games still cannot offer in the same way. For those with such a bent, and with a willingness to engage their imagination and forgive some older design elements, Avernum 4: Greed and Glory will suck you deep into its yawning, cavernous depths.
