To be honest, I don't have time right now to respond to all of this fairly, but I'll stop by for a second to say that these are all very valid and reasonable points. Apologies for the initial harsh response. I'll see if I can get back to this tomorrow.
And really quick, the logic that supports the idea that G2 sold alright (not necessarily well) was that:
A. TLG is likely the only reliable source for sales data.
B. Official TLG social media stated that the line "was successful".
It's debatable if that's evidence enough, obviously; however, just for the record, that is the logic that exists. I've been making the case that none of us know enough to extrapolate in any meaningful way, and I'm unlikely to switch that up.
