The Fallout games are considered two of the best role-playing games ever, so it seems to make sense that games that clone the attributes of those games should be widespread but they aren't. Some games use certain aspects, but there have been precious few post-apocalyptic games made to date, none of which have used a turn-based combat system.

If this is what a 2005 follow-up to Fallout looks like, there probably won't be another.
