The guys at GameZone have whipped up a review of Avernum 4, giving Spiderweb Software's old-school RPG an overall score of 7.4/10. Their conclusion:
Overall, Avernum 4 is a simple looking, old-school style RPG title that doesn't try to dazzle you with anything fancy. It's basically a dungeon hacker's title, but has a decent story, some twists, and a lot of elements that make some of the more big budget titles a lot of fun without all the flash and pizzazz that they offer. If you enjoy RPG gaming in an older style setting which will provide hours of good hack and slash fun, at least check it out.
