First off, I'd like to say that I am extremely appreciative of all the work that has gone into making and editing this wiki. Thank you very much for providing a great resource to the community! That being said, I have a general suggestion which I think will make the wiki function better.
I am a native English speaker with a strong command of the language, but the word choice and number of somewhat unnecessary adjectives on the pages is a bit much. I understand that everyone has their own writing style, but I think the manner in which the pages are written detracts from the effectiveness of the wiki.
To me, the most important goal of the wiki is this: to provide accurate information that users can quickly and easily access and understand. I don't think that the pages are written in a way that's as easy to understand as they could be. As you can tell from this post, I speak English well, but reading the wiki makes me tired. I would guess that a decent fraction of users are not very good at understanding sophisticated English writing due to being young, not being native speakers, or for other reasons. If a decent fraction of users have trouble understanding - or worse, cannot understand - some of the sentences on the wiki, then the wiki loses its effectiveness.
For example, take the following passage, which is the description of Route 10:
In my opinion, this is written in an unnecessary way. Someone who is young or is learning English would have difficulty reading this. I would write the passage as follows:
That's it. Concise, contains all major relevant information, and easy to understand. I acknowledge that the wiki is supposed to be official and formal, but there's such a thing as too much. The passage I presented is free from grammatical and spelling errors, still written formally enough, and much easier to understand. It being concise is helpful because the longer a block of text, the more unlikely people are to read it, which further defeats the purpose.
I realize that what I've just described is fairly high-effort and lower-impact in terms of projects, and I'm not demanding that people slave away to edit all the pages. Again, I am appreciative of everyone who worked on creating this resource - this is simply a suggestion on how to improve the effectiveness of the wiki. As far as why I don't do this myself, I wouldn't want to rewrite the entire wiki without consultation.
(Also, "accessibilizing" isn't a word.)
