Thom Mathews plays through Spawn: Armageddon and has this to say:
"There's a reciprocation that comes from certain games. They give back the love that is given or better yet, they might multiply that love--those rare games that aren't played so much as they seduce the player. Games that make it easy to love them, or even games that offer up an initial bit of resistance before opening up and allowing the persistent gamer access to their hidden treasures.
Spawn: Armageddon is not one of those games."
