I've only been asleep for seven hours, holy crap.
I don't think you understand the extensiveness of the search, Pirate. The characters didn't know if Silovic was even alive (I was betting that he was setting AFK in observe), I wasn't even holding any expectations on an OOC level, we had to pass through the underground twice because of emissions. This is one of the times being accused of metagame is pretty ironic since I didn't know anything about the circumstances surrounding Silo's disappearance, and I didn't even know that the 'Rejects' were a player based group, let alone involved. Nate and Hellhound are also friends (I'm assuming that's McCrae's Reject character) so that's some serendipitous tension set up there. The point is we were not beyond the avenue of breaking into places to make sure our search was thorough. An unopened door underground is pretty damn incriminating, because the whole mentality of the group was 'where would I hold someone if I had kidnapped them'. Of course the players themselves couldn't suspect it was a magic rabbit hole with no ICly representation on the surface world.
Honestly, I don't give a damn if the admin team authorized you to build your secret bases that no-one can know about, and no-one can get into, because they obviously lack an understanding of what makes Garrysmod different from any other medium. The fact that a chain of events, random, strange, and unplanned led to some pretty heavy roleplay-- that an anonymous group of STALKERS talked, upped and explored, getting involved with something they simply stumbled upon, is something that only happens in this medium.
I can tell you exactly the extent of what Osprey metagambled, and that was none. We had told him we had searched everywhere (we literally did), then he said 'there's one place you didn't look'. And that was the door he was always wondering about, but could never opened, he wasn't involved until then because it was our search that sparked the IC motivation to break in through that door.
As for pushing so hard to get the roleplay through, that's on me. I have this weird, stupid thing I like to do and that's roleplay something through whether its 'against the rules' or not because you can always retconn it. I'd rather roleplay, and have it wasted, then not roleplay and have it be a missed opportunity.
I had no contact over SF with anybody involved, and wasn't in TS yelling.
Anyway, underground bases are scummy, you should be ashamed of yourself. The practice is the very embodiment of elitism.
Are you sure you didn't roleplay on TRP?
