When does good gameplay stop being good?

After reading some of the quake 4 reviews from various review sites (gamespot, IGN, ect) I absolutely can not wait to get my hands on it. Why? Well it’s certainly not because of high scores, because quake 4 didn’t get amazing reviews, it got good ones though (around 8.0/10.0). So why then am I looking forward to it so much? Well, lets start with what the reviewers think is good. Generally they all feel that the single player experience is fun, as I expected. It is after all made by raven and they know good game play and story. Where quake 4 lost points was in its multiplayer aspect. One of the reviews basically said its “quake 3 with better graphics”. Well stop me if I am wrong, but isn’t that exactly the point? I am pretty sure the fan base wanted basically the same exact game with a major graphical upgrade. And if that is what they got, this game will be amazing and have a huge loyal fan base. The multiplayer is getting knocked a few points because it’s the same as quake 3? Last time I checked, quake 3 online was a ton of fun with game play easy to learn and difficult to master. Since when does good game play stop being good?
