Wow, I thought console platform fanboys are bad, PC gamers seem to be just as bad when it comes to wanting to say, "NO, WE'RE THE BEST!" Nice way to hijack a thread into a PC > console thread.
Anyway, he's basically stealing a quote from Bungie when they described Halo and not saying it anywhere near as eloquently, which I think is why he's being misinterpreted. Bungie said it better when they said "30 seconds of fun. Now do it over and over again." They're saying basically every 30 seconds, there should be something totally and completely awesome that just happened. Where Cliff messed up that quote is by adding the word repetitive in there. Bungie meant something different every 30 seconds. Not neccesarily new, that would be impossible to maintain, but different from what you just did the last 30 seconds. Basically, never let the game be boring or repeat itself for more than half a minute.
A lot of shooters nowadays including Call of Duty, Battlefield, Left 4 Dead follow this philosophy now. Older games, even fairly recent ones like Half Life 2 (the original, not episode 2) don't always do the 30 seconds of fun over and over. Granted it's a great game and there's tons of moments of fun in there, but there's also the older legacy design of late nineties shooters where you would walk across a landscape for 30 seconds without much anything interesting going on around you.
