from the polygon review:
This to me is another problem in the whole games industry / games journalism paradigm. What's the point of "reviewing" a game with publisher reps pacing all around, within a set time limit? It's bullshit.
To be fair, I've gone to some of the MS review events before (not for Halo 4, but for other titles) and they've basically consisted of the following:
1) MS rents out local meeting room space.
2) Everyone has a dedicated system setup.
3) Food is provided at regular meal times.
4) Devs and PR reps are on hand for interviews or if you have a specific question, but they don't bother you. If you never walk up to them, your interaction is basically "Hi" and "Bye."
5) Depending on the space rented, hours are either all day or 24/7. You're free to come/go as you please.
I've never felt "rushed" at a review event, any more so than playing thru a disc at home. IF anything, it's more like a return to playing as a kid, when you'd get a new game, crack it open and play til you beat it.
