Time for a spoiler thread maybe? To keep this one clean.
Don't see why we need to do story discussion before the game comes out when the main concern is performance and portions of gameplay. The latter can be vaguely termed "the middle" or "___ many hours in" to avoid any story stuff. Heck, folks can post story impressions without giving details, such as this character worked or maybe that the religious themes were off-base.
I'm sure most here with early copies can restrain themselves for a couple of days. But I'm not going to put one up (Of course that is to say Cyan, Andrew, or whoever else who contributed to the OT don't take up the honor themselves) prematurely in this community. Not everyone is going to have it day 1 and the temptation of that thread just being there is bound to cripple a good number of folks.
Could be early Tuesday morning, or it could be Thursday evening. But before the release in the game when the only thing that notably leaked out was the ending (and mostly just a short, troll phrase at that) isn't going to force a spoiler thread up before the game's release.
Tldr; It's not going up until most of the community here wants it up, and all the lucky fishes out there can be courteous in the mean-time with their impressions.
