I imagine they are done with D&D. It's obvious they're not fans of the ruleset
I think you're wrong there. This game is clearly a work of love, and from the get-go they were always talking about how they play tabletop. But the final product is a computer game and must be designed as such. It must be fun to play as a computer game, for which the ruleset is not designed. There's also the matter where something of this budget, must be able to be played by those who aren't at all invested in D&D. This held a little less true for the original Baldur's Gate, which was more of a niche game, but that too is in a lot of ways a poor representation of the AD&D ruleset. Because it's not a tabletop game.
Then, the rules lawyer is always the worst player at the table, as they get in the way of having fun. D&D is about speaking to your imagination. In every player's handbook since the very first - it says - paraphrased - That the rules are there to give you a baseline, but that they should never get in the way of your world, your imagination, your fun; and you're encouraged to change them up in your game. Well, they did just that.
I think that, with all the infrastructure they built and now in place - they might be in fact, be rather anxious to tell another story. Could be D&D, could be something new or an add-on for this game. If they do, they can have my money now. Just, have a good launch party and a few weeks off, first.
100% agreed! (except for Pathfinder, i like Golarion as well)
Oh, me too, it's all fine - and if that was our starting point, that's what we would have played. But just for convenience sake, we swapped things around in Adventure Paths, so we didn't have learn a bunch of new lore while playing. It also makes more sense in game that major deities are just known by everyone and don't require extensive explanation. The only reason we played Pathfinder was 4E, anyway. 5E is perfection, though and we're not likely to go back - or even update to something newer. If you start your level one adventure and Demogorgon shows up, that instills something far greater than an unkown Demon that kicks a Dragon in the face. Our Paladin and Cleric conversing with Torm has more impact than explaining who the new deity is.
Give it another go, maybe you’ll appreciate it more.
I just might, but it's been such a long time, I worry it'll be the same experience.
