Too much hype spoils a game, not so true. You have to remember that Doom3 was almost entirely hyped by the community. The opposite would be HL2 which was completely hyped by the company at any chance possible. The fact is, hype matters very little in comparison to the end product.
Let's talk about Doom 3 being boring. If you talk to anyone, you will inevitably hear that Doom 3 got boring very quickly (hell, it is mentioned several times in this thread). The fact is that it is difficult for someone to enjoy a game that is too scary. The game quickly puts you in a mindset where you no longer want to be scared, you begin to expect everything and to move with a certain level of precision. This mindset is what is boring. Doom 3 hit this 'too scary' wall and went right past it, forcing people into this mindset for a better part of the game. After awhile, your guard is simply never down. This is poor design, and I hope more developers can pick up and understand this concept. A game that is too scary can never be enjoyed properly by the masses. If you look back, every extremely good scary game has walked a fine line, where scary parts come in small doses when you least expect them. I take Eternal Darkness as the perfect example, it only has one TRULY scary part, one. This part will take every single player of the game by surprise and leave them questioning every turn for the rest of the game.
For the record, Quake4 and Prey both captured my attention when I was viewing all of the E3 footage. So whether or not the engine will go places has yet to be decided. I'm not going to immediatly subscribe to Unreal3 being some sort of god's gift to engines. That is just more hype that people love to buy into.
As far as the article goes, much better pieces have been written and that guy really doesn't state anything beyond the extremely obvious. He almost touches on what made Doom a great game without really analyzing it. He at least acknowledges Quake1 for being what it was.
