This game is amazing. If you ever thought you might like Bejeweled, but the casual gameplay alone just doesn't do it for you, get this game
. It's still Bejeweled at its core, but you play against AI opponents, it comes with a fantasy setting (a kingdom in need, fantasy creatures to fight against), RPG elements (character building, spells that you can apply on the Bejeweled "battlefield"), strategy elements (conquer cities, upgrade your own palace with useful features), a story-driven campaign, a truckload of quests, and optional special puzzle challenges.
I played this some months ago and I'm still amazed how much the devs made out of the rather simple "Bejeweled" concept. I especially liked how the different character classes and spells allow for completely different strategies in the Bejeweled "battlefield", and I created several different spell combinations for my character to tackle some particularly challenging battles. This game, to me, is an almost perfect blend between casual and "hardcore" gaming. Often this blend is attempted by dumbing down a formerly complex game, and this usually fails. Puzzle Quest does it the other way round: It takes an immensely successful concept from casual gaming and enhances it in so many ways that the end result appeals to hardcore gamers as well.
Sorry for the sales pitch. It's just that I really like this game. :)
