The latest Version of Age of Wonders is Shadow Magic, a sort of improved Age of Wonders II. So you should go for Shadow Magic if you want to play this game, and skip Wizard's Throne. I have heard the first Age of Wonders was somewhat different, but I would have to compare notes with Spoon to know. (That, or simply pick Age of Wonders 1 at the local store; cannot be a bad buy for one buck after all)

Back on the topic of Age of Wonders: I would say it is an interesting game, especially for single-play (and better than the Heroes of Might and Magic series if you ask me). My main gripe with the game is PBEM, where battles between players are resolved through a very peculiar system. I do not know about the third-party content offered by this game though.
