Spectral Souls

Was a series of tactical RPGS by Idea Factory, who had created several other Japan-only games of similar nature; Aksys Games and NIS America eventually brought their series over to the use in the form of Blazing Souls Accelate and Spectral Souls: Resurrection of the Ethereal Empires respectively.

The Series had a spin-off, Radical Elements, which was more like Warcraft and Starcraft than its predecessors. Also featured as part of the Massive Multiplayer Crossover with several other games in Chaos Wars and Cross Edge.
