Carradice: procedurally generated world = lazinesssssss of the developer.
Imago: Creation of the sophisticated algorithm also requires a lot of work. It can be equally interesting to navigate randomly generated environments, leading to some unexpected findings and encounters, as it is in well designed world. The most interesting thing is that you never know until you try.
Also, good level design follows distinct set of rules, which can be implemented in world generation algorithm. Check the analysis of the original Zelda (which this game "tries to emulate") level design, and you'll see those rules (lock and key concept, enemies placement, etc.) and how they are applied.
I'm not saying that this game has better level design than LoZ or any other "handmade" game, and I'm aware that results of procedural generation can be uninteresting, but it is definitely wrong to call software developer, who wrote the algorithm that creates something playable, lazy.
Sura algorithms require work. I am happy to agree with that. However, people write algorithms in order to not having to do the work by hand... In this case, making interesting game areas one by one.
From the point of view of the player, procedurally generated worlds add to replayability. They tend to make game areas anodyne and soulless.
Again, for some games and players it may work. Diablo and Torchlight were mentioned. You can add roguelikes like ADOM (another fashionable thrend nowadays). The first being a legend and the second a gem. But, despite being a gem it becomes repetitive after you have seen all the tricks.
Who will you talk with in the levels? What kind of quests/missions might you find? What kind of dialogue? The best procedure will not generate a
Baldur's Gate. Nor a
Raptor nor a
Tyrian, and the last ones are not dialogue-rich games...
Hoping the best for the developers and the players who want to give this particular game a chance. Just probably not for me like other games in this particular vein that were disappointments, although I would be glad to be surprised--who does not like having fun in unexpected places? :-)
