@beardalaxy I think many of the delayed games suck because they were trying to keep up with the industry trends instead of making a good game.

Duke Nukem Forever is probably the best example. The developers wanted it to be on par with the most advanced games at the time because DN3D was released a month before Quake and looked severely outdated because of it. So they were constantly changing engines and starting from scratch.

Though I haven't played or know the development story about any of the games on the right side of the image, so I don't know what happened with those games.
