Imagine having the last few years of your life publicly defecated on because you opted to ship instead of delay.

Ryan Holtz (of Minecraft/Mojang/EA Tiburon fame) was on the release team for Superman Returns. The game (and especially the parts he worked on) was very competent; it just didn't mesh well as a whole. He's understandably really sensitive about the whole thing, even years later. It would be good to keep in mind that there are human beings with emotions behind these games.

NMS underdelivered, but it was still a beautiful game. In this era of DLC-as-bugfixes, I wouldn't be surprised if many of the features people complained about were implemented later.
