I've preordered a copy. I agree with the comments that DO looks like it'll be the easiest-to-mod rpg game yet. Without that aspect, indeed, it'd just be a decent old school rogue-like (with some inventory issues.) But with the randomization + modability (a word?), it seems like it'll have a long shelf life. It's true RSII has both these features, but it looks like the time involved in creating a new "world" from scratch will be immensely shorter with DO.
All in all, I'm expecting to see lots of creative things come out of the mods to it, including some mods of my own hopefully.
