i'll wait till i read the review from my gaming magazine before buying, but i dont expect a failure from these guys. Time will show anyways. I wont check the videos before they're close to release (i think it was about mid-late 2007).
its concept will be repetitive (as both Diablo games were). The dungeons will be random generated (just as both Diablo games) to make it worth it to play over and over again. They said they'll also have some random quest pools that the game will pick quests from (the good old Diablo 1 way).
I'll buy the game anyway to check it out. Looks promising, now they'll only have to stick to the old Blizzard quality standards.
