We also loved D2....and D1....and Torchlight.......and POE.....and I have a ridiculously huge amount of hours in D3.
We are huge fans of ARPG's and even bigger fans of ones that are co-operative. So reset assured we are focusing on many of these points for our follow up game.
We have made really awesome progress over the last few months and hope that we can share some of it soon without putting our development cycle at risk (showing something that doesn't convey the theme/heart of our game). Our fans have been extremely patient with us as we build our new game, we know that waiting is hard and we hear ya!
Thanks for playing and supporting our game!
