Yeah, it also suffers from the over-powered protagonist trope found in a lot of fanfics. It has good elements (of what I've read thus far). I think the story could have been better if it focused on a few crossovers and technologies instead of going "here's a completely unrelated power/ability from a new setting", but the premise (earning rewards for writing that result in random abilities from different franchises) doesn't really lend itself to that.

Like, you could still have the different members of the forge and lean into a single source of the tech. Warhammer 40K could fit, given Tetra and some of the initial abilities/power. So you could keep most/a lot of the summit meeting events.

A fanfiction where the author gives the main character good boy points for writing more words is kind of the extreme end of this, though. Web serials and fanfiction tend to be overly verbose and meandering, and the Methods of Rationality is very much on the less verbose side of them, but by the standards of traditionally published fantasy and sci-fi it is wordslop.

The Silmarillion is riveting and concise! I will grant that it's not a novel.
