BG3 is irrelevant to the genre.
Companies will continue to do what companies want to do, which is often sell husks of a game with plethora of MTX to maximize profits. Which is something that BG3 doesn't do.
Meaning, BG3 won't have any more effect on the genre than Elden Ring which is also a popular RPG with no MTX.
The bigger impact on the genre would be things like the success of Diablo: Immoral, the CoD franchise, Fifa etc. Games from other genres but earn tons of money through MTX ridden shovelware.
As far as RPG design goes, BG3 doesn't do anything particularly revolutionary.
Even as far as "Sex" goes, Witcher had nudity ages ago. That hasn't made everyone start putting nudity and sex scenes into their RPG's.
BG3 has the added part of being based on DnD, which unless other RPG's are also being made based on DnD, won't translate into other games. Since DnD has its unique rulesets (Things like Standard Actions/Bonus Actions/Reactions, Extra Attacks, dice lots of dice with its Critical Miss and Critical Success rolls, how stats work, how skills work etc)
Honestly, I hope that RPG designers continue to improve on things rather than copy BG3. For example;
- If they want to add in romance. Make romance better. So that relationships are deeper and less "Do nice thing. Get sex" (I like how BG3 has voice line changes for companions with positive relationship statuses for example)
- If they want to add party limits but have more companions than the limit, make it better than "I want you to stay in camp." "Are you sure?" "Yes, I'll find you later" "Okay I guess I'll eat dirt then". Make it so inactive companions are doing something, not just standing around waiting for their turn to join you. So that it feels like your entire crew is on the same world saving adventure, even if your active party doesn't include them (Heck, they could be out doing their own stuff and you could meet them in the world as they're doing things. Imagine progressing character stories by finding them at their story locations and helping them out even without them being an active party member. Oh, now you also have reason to equip your ENTIRE crew? Neat)
- Continue to flesh out choices and consequences. One of BG3's strengths is the lasting effects of choices. This needs to continue to be a more relevant part of RPG's and we need to be rid of the plague of faux choices that dominates the genre.
2) removing all of the strategy by redefining attributes so every character needs all of them and so their effects are "linearized", i.e. so there is no major impact for raising attributes to a certain level.
Honestly, I think it's great design to make all stats useful on all characters.
It puts more emphasis on choosing how to build your character. So it's less "Wizard = Dump everything but Int" and "Barb = Dump everything but Str/Con" and more about prioritizing stats, dumping stats leading to a tradeoff where you become weaker in one aspect of your character for the gain of pumping up another aspect (And a WAAAY better method of preventing stat dumping than by hard limiting stat choices, like how here in BG3 you can't have less than 8 in an ability score and can't put more than 15 pre-racial bonus)
That's not removing strategy, it's adding it.
It also effectively deals with the other silly aspect of common RPG design, which is separating power stats for no reason. Like there's no point to having 3 items, one with +8 Strength, one with +8 Agility and one with +8 Intellect if they all just do the same thing of add +8 damage to the character when you could have them all just share one item with +8 Power. (DnD based systems at least provide purpose for different stats with additional effects, like trickle down into skills and secondary benefits such as Dex providing AC)
The only qualm with PoE's stats is they continue to use the traditional names so it's kind of odd how a Wizards Fireball gets more powerful because... He's hench? Or a Barbarian cleaves in a bigger area because... He's smart? With this also translating awkwardly into various ability checks (Like, when my Wizard had to punch down a wall because my Barbarian wasn't strong enough...)
