I got the demo and tried it. After finishing the demo I had a few things to comment on.
I couldn't believe how poorly it ran on my machine. Admittedly I'm low on RAM (only 512) but I've got a 3.06 GHz P4 and a 128MB video card that should carry some of the load. Definitely a case of don't bother if you don't have the computing power to work it, though admittedly I didn't try too hard to get better performance out of it.
I liked the idea of the customizable skill sets. At level 6 I hadn't seen much but the idea seemed cool.
Overall it didn't really grab my attention, but I'm not sure why. I think it doesn't have a lot to add that D2 didn't already have, or maybe it was the choppyness. In some ways it felt very much like a D2 clone, with the inventory screen, quest options and skill trees reminding me very much of D2.
My rating 6/10 not bad, but not exciting enough to pay full price for.
