It's hard to recommend FIVE: Guardians of David to anyone. Fans of action RPGs have literally dozens of better games to choose from. Even gamers who would like to play an RPG without being assaulted by bloodshed have some excellent choices, such as the Torchlight games. Aside from the novelty of the Biblical theme and story, FIVE: Guardians of David's gameplay ignores a lot of what recent action games have added to the genre: strategic groups, tactics, character development, customization — FIVE has none of these things. Its heroes are bland and its enemies even duller.
With so many interlocking systems, Thea: The Awakening is a bit of a Frankenstein of a game, but kudos to MuHa for bolting together everything so seamlessly and for trying something new, though it might be time for developers to put card game subsystems on ice for a few years.
