Modern settings are inspired by old ones. In this particular case, Pillars was supposed to be inspired by Forgotten Realms. And I can sympathize with people who can't tolerate that they were promised basically a successor of Baldur's Gate (which setting was Forgotten Realms) and were actually given another type of fantasy. One that included many themes post-renaissance (like guns) and a different tone.
And I can have sympathy because if it were me, I would be angry too. Like anyone who like a genre and others come to disrupt it.
This a matter of preference, I have never disagreed with someone who said they prefer medieval themes, medieval aesthetics or medieval settings at large. LOTR is a thoroughly medieval setting and a very good one. Forgotten realms is boring, but whatever.
Yet many people here came swiftly defending and justifying these decisions saying basically that people don't understand big brain "historical" guns. When in reality, these "historical" guns are the ones out of place from the view of someone expecting his or her genre to be respected.
It's not about historicity, never was and I have never talked about historicity or "realism". I talked about two particulars, one is themes and other is coherence. If you don't want renaissance setting, don't make one. Really simple. However this is not what is happening, people do make renaissance settings, everything in the setting is renaissance and sometimes even beyond renaissance by far, they use renaissance clothing, renaissance armor, renaissance architecture, renaissance social structure, renaissance aesthetics, renaissance philosophy, renaissance weapons, minus the guns.
Any type of historical or technological pedantry don't belongs on fantasy.
Definitely, the argument about guns being some sort of insurmountable or immediately altering technological invention is pedantry of highest sort and doesn't belong in fantasy. Fantasy can easily have guns. Case in point, pillars is a fantasy setting and has no trouble including guns in it.
If people want forgotten realm settings and its other derivatives they should demand them, BG3 is one for example. However the argument that there cannot be a fantasy setting with guns in it, or that guns are immediately violating concept of fantasy, or that renaissance doesn't belong in fantasy and shouldn't be made are demonstrably false. That's what was being discussed and that's what you responded to, not that people demanded forgotten realms and didn't get forgotten realms.
Here is the thread that was linked in that discussion:

Here is the exact quote for your convenience:
Obsidian, if you want guns, make a Fallout-inspired game (which I believe you are involved with in Wasteland 2). Stick to fantasy and leave guns in the steampunk, post-apoc type games. Please.
