I bought this game on a whim, hoping I'd bought something worthwhile. Boy, was I rewarded! There is a story there,but you can ignore it for the most part. You do need to complete the quests if you want to easily get your spells and abilities. But once you reach a certain point, you can just run around kill everything (depending on you class). The first character I created was a Battlemage. While starting off fairly weak, they become near unstoppable badasses in time. This game is a great game to satisfy your Diablo 2 cravings if you can't afford the battlechest, and a great thing to play even after getting Diablo 2.
I enjoy the class variety, even though I could never really find one beside the Battlemage that I truly enjoyed. But, of all the classes there is alot of great choices for all play styles. And the loot system is very similar to Diablo 2. The only thing that this game could improve on is the stats and attributes screen. It's kind of weird to use when you're starting off.
I recommend this game to anyone who enjoys pure hack-n-slash and loot collecting.
