"Well made and (fairly) innovative"
For anyone just joining the Diablo universe, you will find this a surprisingly welcoming game, with a short learning curve and fast paced action, you'll find yourself stuck in in no time. Also, the system requirements for running the game are fairly low, I'm able to run the game at just below high settings with my i3-2100 processor and its integrated graphics.
One, very interesting part of the game is the real money auction house, an in game facility that allows one customer to sell virtual goods and currency to another. Not only does this allow people who work within the virtual trade markets to earn a living without violating the terms and conditions of the game, but it also presents the opportunity for devoted gamer's to make a profit from their hard work and long hours.
The only downside to this though is the lack of proper social interaction within the game, although they provide an automated player match up system, in which you can be randomly placed into a party of people to play through the game, there's no "designated" area where people can gather and converse.
Overall, whether your a fan of the series or the genre, it performs well at both ends of the spectrum.
