Adding words for a bunch of people who might not want to read MORE words might not be the best idea.
Some JTRPGs tend to use a bunch of comics for the more complicated stuffs; At the same time there are some western designers who believe "Always put one small picture in every few pages to break the monotomy. Quality or relation doesn't matter in this regard." Both sides use simple powerpoint-type graphs quite often.
Wall of text is scary regardless. (This thing here should be example enough. 0rz)
You don't need quality artists. How about this: Try to make a few small, simple, DVD-setup-manual type of instruction-oriented pictures (Not the semi-publishable manga types you see in JTRPGs; That'll be overkill right from the start so DON"T DO THIS at least for now.) And see how far it can get you. Maybe it can get you some new ideas to show it to others?
==================================================
As for WHY we make games and edits: I myself never ask WHY anymore.
(Especially when I've still been doing that after decades... Reasons and points only get you so far.

)
In the hobby, everybody would eventually get to this point. Maybe for a lot of people that's like for 15 minutes, for a few though the idea sticks.
But do we NEED new systems?
Heck NO. To put it simply,
we've never NEEDED anything beyond AD&D2ed at the first place. It's the basis of a rule, we want a rule, we houserule rules when necessary. Done.
Every other games out there are only by reason of Market Forces, and none of them are ever "needed" per se. And even if you discount that, the most we "need" for systems are probably the top 10 that dominate the vast majority of TRPG market. - And strangely enough that list won't include PF as it is a variation of D&D that you can just houserule into D&D. v=_=v
But why do we have so many countless other stuffs out there? Well,
why not?
"Wanting to do something" is itself reason enough. Even if the person in question has never read any other thing out there except D&Dcore, and his product is only going to turn into a sad heartbreaker that might work even worse than the original. - Not that I am saying it is the case here. I ain't gonna say anything about this thing at hand here is my point if you catches my drift. v*_*v -
I really don't have any reason to stop it. Market Force will deal with it whether we like it or not.
(Plus we all have something we do that, in other people's eyes, are "pointless". Like playing TRPG for example... AHEM. Anyhow POV is important.)
If nothing else, we always have the choice to do things "for the lulz" as long as it does not hurt anybody else.
Plus, waaaaaaaay more importantly, sometimes miracles do happen. If we keep asking why there won't be PF, nor will there be Lamanation of the Flame Princess, 無限, and probably not FATE. Heck we won't have Tesla making cars if we keep asking why... Okaaaaaay, bad example there. !!!=3=\
(
WE WON'T HAVE KURATAS IF WE KEEP ASKING WHY!!!!! DARN I REALLY WANT ONE OF THOSE.

)
Maybe it will turn out great, and we all reap profit; If not, nothing is wasted on my end, nor on his end as he'll probably learn to either make something better next time or stop trying at all, neither of which has anything to do with me as well.
So I'd say let them go for it. Just my own .0000002 cents. v=3=v
