Addictive Circle Fun
Puzzle Quest: This one had me seeing circles for weeks! This is an RPG, but instead of fighting with swords, you fight with Bejeweled. Brilliant! The story is so bad, I was just begging for opportunities to skip past it, but the actual battles were puzzlerific! And the system to get new spells and character upgrades was fantastic. I beat this game, collected all the spells, captured all the monsters, and realized I would never play it again. So to eBay it went. But before then, I had a great time with it.
