1. I didn't say only people who lived there could know. If you studied it (aka. more than just using a wiki, but actually going out-and-out to the place itself, studying texts and etc.), or could convince me that it was both justified AND wouldn't be abused stupidly, then I'd be happy with it. Alan clearly and definitely doesn't fulfil any of those, unless he's somehow an interdimensional planeswalking scholar man.
2. I haven't voided any of Alan's backstory. I've voided his ability to metagame because that's the issue here, not his backstory. Furthermore, it's not my fault you made a character with the potential to metagame, nor is it San's, or anyone else's.
3. Inveterate gamer knowing a basic thing? Fine. Inveterate gamer basically knowing everything about the setting (i.e. what Alan did with Metroid)? Unadulterated bullshit.
4. You've been hauled up too many times over it, and haven't known when to stop metagaming to the point that the actual GM of the game wants to either nerf Alan or kill Alan. If his metagaming wasn't a problem, I wouldn't have had to severely restrict it, period.
Argue the logic or lack thereof, or whatever you feel is rational, but I'm sick of having to come back here to see Sanure pissed off at you because of metagaming and I'm also sick of people complaining about metagaming, so I'm ending it for anything apart from jokes. And if you want to overturn my decision, persuade Sanure to convince me otherwise.
Yes, I'm going to be unreasonable. No, I don't care one dot, as we've had far too many complaints to not do something about it. My decision, unless I feel otherwise, will remain.
