Has-Been Heroes isn't a bad game, but I wasn't excited to start over after my first loss. After coming to understand the mechanics and strategy better, I am enjoying it to some degree, but I don't feel any less frustrated every time I lose. The only thing driving me to play more is my inner completionist, but if you're looking for a game with a compelling story and more to it than just unlocking more in-game items and spells, then this might not be the title for you.
The random nature of so many of Rogue Wizards' elements guarantees experiences that are dynamic, but the repetitive core gameplay and tedium of inventory management can also make them monotonous. The Story mode's narrative doesn't add anything to make the gameplay more compelling, so you may be better off with the Gauntlet mode's endless dungeon. Either way, this game works best in casual play sessions.
