I'm really looking forward to No Man's Sky and will probably buy a PS4 just to play it.
I am a fan of procedural generation. I am old enough to have played Elite on an Apple II and been blown away by it at the time. (For younger readers, No Man's Sky is basically an elaborate modern reboot of Elite)
However, I know as a developer and game player in his 40's that there is a reason everyone doesn't use procedural generation for everything and I know that we all were more used to putting up with repetitive gameplay in the 8-bit era. Procedural generation is great for demos but is hard to get right for games. Demos need to look cool. Games need to be fun. It is hard to procedurally generate fun.
Another personal data point for me is how dull I found Sid Meier's Pirates! on my iPad even given that I remember loving Pirates on the Apple IIgs in another life and given the fact that the iPad version is pretty much a straight port of the original. Pirates was not exactly procedurally generated -- the map was fixed on the realworld carribean -- but it was an open world game and which countries were at war with which when and where treasure was located etc was randomly generated. I remember I used to like sailing around and doing pirating and trying to maximize yields of each voyage and plan out where I wanted to go, etc. Recently I played the remake a little but had a feeling of "Is this all that it was?" So maybe my tastes have changed, but hasn't everyone's?
