This is really wishful thinking on my part, but I'd like to see a product that alters d20 Fantasy classes for d20 Modern, and vice versa.
The idea isn't that it changes any class features, but rather, gives an alternate list of class skills for each (e.g. do Wizards in a Modern setting have Computer Use, et al, as a class skill?), along with alternate bonus feats, altered talent trees, etc.
Basically, stuff that'd make it practical to use Fantasy classes in a Modern game (like
Urban Arcana, but moreso) and Modern classes in a Fantasy game (for a low-magic gritty game, for example).
Temporalty, from Dark Quest Games, did some stuff with this, but didn't take the idea far enough.
But like I said, this idea is just my wishful thinking.
