Id be willing to bet that it gets deeper and more complex over time. Lets not forget that it is still bleeding edge in terms of what it proposes to do--an infinite world is amazing!..though like you said, the storyline and other issues like that will make it seem boring for awhile.
If only they could mix that with a system for people to really create and sell amazing items for use in game...or players being able to create their own quests and add depth to the game world (or should i say multiverse?) ;)
Gaming is going to become so powerful in the coming years...i can't wait (not that I have much time to play, but I still do love them!)
RE: Despite all the hype, don't forget that No Man's Sky can be a total disaster
