Actually thinking on, I've always liked the idea of a 'Twilight 2000' type scenario, where isolated groups of the protagonists are forced to band together to survive against other similar groups. If we were talking a near future scenario the 'action' would be that bit further East. Again it would mean including some more Western European types to the already existing range, along with more civilian types. Plenty of present day vehicles from various sources about and it's pretty much along the lines of what's already available anyway.
