This sourcebook discusses dimensional travel for Champions and is not only usable with other Hero System games, but with any game. The discussion of the "who, what, where & how" of dimensional travel is truly system generic and not genre specific. There are suggestions for mechanisms and reasons for inter-dimensional adventures as well as tips on keeping them interesting.

Likewise, the section on alternate dimension creation is system generic though tilted slightly to the comic hero genre. Still very usable by anyone for inter-dimensional visiting or even alternate dimension campaign creation. The treatment of alternate histories easily makes this a tool for original campaign world creation.

The 5 detailed and 26 one page alternate dimensions are full of great super hero adventure seeds. All are interesting as adventure locations in an existing campaign. Most are easily expanded into larger campaigns or mini-campaigns, Horror World, Nazi World, Rome World, Undersea World and others come to mind. Some are clones of other game systems campaigns: Horror World = Rifts, Dream World = Sandman, Cartoon World = Toon, Disaster World = any post holocaust, Magic World = any magiteck, Monster World = gothic/modern horror (Vtm or Night Life), etc.

Any Hero system gamer should consider this one, after they already have Lands of Mystery and before Alien Enemies. To Hero gamers it should be worth the cover price. To users of other systems, its value varies with genre and system. If you can find it on sale, or used, it's a good gamble for usefulness.
