Ok, just to give some clues...
As for the "Nothing except that you bring with you" thing... not that that is a bad idea, but I think my Lenny and Carl quote is kinda there to discourage that kind of thing. There is a 'thing' there of some description. It is indeed important to measure your approach to the door, but I will make it clear that that importance is in context of the Door, and what is behind it, being a genuine phenomenon. In fact, many of you may well contest Lo Qi's prioritising of the approach to the door, and think it will be much simpler if the Oracle will just tell you. This may be true but it is to ignore several important things about how Matrix games work. It's just like how last time, the oracle could have told you what was going on with Jericho, but it was impossible to really appreciate the situation unless you lived through it, which is what the game was about. Same deal here. well.. actually kinda the same deal, anyway. It's not as if this is a puzzle you can live through as you can Jericho's journey- you already know all there is to know about it. If you knew any more the test would stop existing.
Suffice to say that this is a test of blind decision making with genuine consequences, of you either turning down a good thing, or accepting a bad. The value of that decision is really in it being a test of character. The consequences will still be there to be had, regardless of how that test goes.
People will be thinking "That would have been much less hassle if we had just been told!" afterwards, though I would like to think they were Combat Path people. Philo people should appreciate the test for what it is, even if the test has no value compared to the consequences of your decision. The test does have value, but only personal value- would you open the Door or not? To answer that, come crunch time, is to say something about you
Hence, the matter of the door is very much a matter for the Philo people to consider. Combat people CAN consider it, of course, but it's not what they are there for. But it;'s the blind test I am talking about there, not what is behind it. Guessing what is behind- the idea of this thread- it is pretty much irrelevant to the blind test! So that's open speculation for you all (though if Philo, or even Combat, players want to use this thread to discuss the blind choice as well, feel free)
Secondly... yeah, the door is still relevant. It's not a Zeiton.
