There were a couple people in the comments that said the title threw them, not the GG controversy they had expected, but I think the vast majority of folk just don't know about it.
I really think they need to update that whole intro paragraph, because besides from being untrue it also misrepresents their adventures and turns some folk off.. and I don't think it'd change the appeal their current audience if they fixed it. AFAIK that paragraph is still on all of their stuff...
I don't think it requires any changes from RAW- creatures that're using darkvision to see you in darkness don't see you :)
If you mean the extended darkvision for you? That works as-is too. You get darkvision, or it's extended if you already had it.
I'm not entirely clear on your question- I assumed we were talking about light and vision mattering to PCs. With regards to NPCs, I almost always give them torches or lanterns, because that's how the world works in my head. The NPCs in my world aren't trying to get around someone having to hold...
I also try to make light matter- but in DND5e between darkvision, devils sight, and (IMO most problematic) unlimited cantrip castings, it can be tough to completely turn the lights out on the party.
The best advice I can give to making dim light table-relevant is to always ask "ok youre sure...
I hate to attribute too much to the guy, 'cuz I've been playing TTRPGs for almost 30 years now, but Matt Colville definitely cemented some ideas in my mind which match a lot of your assumptions:
Adventurers bring trouble, or they follow it. They think money can solve everything. They're drifters...
Agreed that consistency and a sense of direction's very important. There are some indie ttrpgs that use old art that's fallen into the public domain, and it can be very effective if they curate it well so it's all a consistent feel.
True- but to be fair, I don't know that they said that those parties that ignored the fireball-throwing mooks won their fights- so you think that if they're getting whooped, or if they lose, they'll learn and use better tactics in the future.. this might be the case, but it might not- because...
I appreciate that you posted this, I was curious to see if anyone was going to say "no ttrpg book art doesn't matter to me," because to my mind it'd be like someone saying "I don't like (any) music" so I couldn't imagine it. Thus I appreciate you sharing your perspective!
