I agree that picking Numanuma as a setting was a horrible, horrible decision, largely because of the reason you state: It as little to no consistency, and it's the setting of "lol I dunno" and "oh weird xD". However, I disagree in that it wasn't the worst decision. After all, compare it to the setting of Golarion, which isn't as bad as Numanuma, but is still a terrible kitchen-sink and probably easily in the top 10 of shit fantasy settings, yet Pathfinder: Kingmaker had no real issues making sense of it and creating a somewhat self-contained narrative that makes sense within the confines of itself - even when there's hints to the wider world (such as Numeria) it's not on the level of retardation that the setting would actually warrant in order to make a lick of sense (when you run into the Technic League, they don't shoot you with laz0rs, etc.)I concur that picking Numenera as a setting was the worst decision of them all.
A setting where anything goes is not a setting at all, it's a Theme Park: Weird Shit.
Combine that with ruleset which is better suited for a point&click adventure than it is for a CRPG and with Monte throwing tantrums over political bullshit and you've got a recipe for disaster.
So yeah, Numanuma was a horrible choice for a setting, and the Cypher System was a horrible system that came with it (and simply do not work properly in a CRPG anyway), but a far greater issue is that they failed at even using it and creating the necessary framework and narrative structure that would've made Numanuma at least "OK".
