Be warned: If you have yet to play John Wizard's previous role-playing game, Lilly & Sasha: Curse of the Immortals, you'd do well to work your way through it before tackling Lilly & Sasha: Nexus of Souls. This sequel picks up right where its predecessor left off, and despite a quick recap of key scenes from the previous game, its story and characters are so intertwined with those of its forerunner that players who didn't play Curse of the Immortals will be left scratching their heads some of the time.
