Dear Larian Studios!

So far I like your game, and in many points so far your game is one of the most correct one in details among all the games which play in Faerun. But in the character creation have some mistakes which is a little bit disturbing:
- First: the Drow (Dark-Elves) is a sub-race of the elves
- Second: the (true) High-Elf(s) is one of the less common sub-race even among the elves (mostly live in the Moonshae Isles), so it's a bit funny, (even after the "Spellplague" and the "Second Sundering") that for all of a sudden every elves and half-elves around Baldur’s Gate became a "High-Elf" (or half high-elf)
The most common elf sub-races in Faerun is the Moon-Elves (Silver-Elves) and Sun-Elves (Gold-Elves) The "High-Elf" (Eladrin) is an absolute correct "collective noun" for the Seldarine Elven Races so it's usable, but not exactly corret as sub-race from the earlier mentioned reason.
Suggested solutions:
- For the Drows: not neccessary to put under the "elf tab", just add a line(s) like this: "Drow also known as dark elves, were a dark-skinned sub-race of elves ....etc." (from the D&D guide book "Forgotten Realms Campaign Setting”) to the "race's description" and after can continue the description with the original lines.
- For the High-Elves: again don't need to put the moon-elves and sun-elves into the sub-races if you don't wish it (but personally I think it would be better), just add some additional lines to the "race's description" about the moon-elves and sun-elves, or just correct it like this: "High-Elves (Eladrin) is a collective noun of Seldarine Elf Races in Faerun, among them ....etc." and after continue with the original description.
I know, both of this isn't a "collossal or catastrophic" things, but both can be corrected without any drastic changes, just with some little "cosmetical" efforts. And if you do it, it made your game more correct and more "Faerun like" which can be a huge point for the players who know the Forgotten Realms not just from games but the hundreds of novels what already published in the Realms.

Other racial things/ideas:
So far it looks like (at least for me) the story’s main plots is around the Illithids and some of Shar's secret plots.
(tadpoles touched by Sharran "shadow magic")
- In this main story settings it's a huge opportunity if you can play as Aasimar (for example aasimar paladin/cleric of Lathander), and a colossal missed chance if you can't, especially because (from the "planetouched" races) the tieflings already have among the races. Not to speak about the memorable conversation chances between the Sharran Shadowheart and a this type of M.C.!
- The Duergars (Grey Dwarfs) already have in your game as enemies and NPC’s, but not as a playable sub-race of the dwarfs, which is I think again a huge missed opportunity because they are the other race in Faerun who hate the mind flayers equally as the Githyankis.

Other opinions/ideas:
In Faerun every "faithless" soul after death ending in the "Wall of the Faithless" so deities and religion are important even for the common folks. From this reason it would be good if the player can choose a deity in charater creation not just for clerics, but (even remain in this way) this isn't colossal problem as well.
The more bigger problem is (which connetced to this topic in a sort of) many characters and class can make some really and absolutely illogical and irrational "mistakes" in the game:
For example: in the "Temple of Jergal" (next to the wreck of the Nautiloid) the party need to do a "perception check" to recognize "Jergal's Statue". The funny and "illogical" event:
-1st time my party was M.C. Human Cleric of Kelemvor(!), Lae'zel, Astarion, Gale, perception check to recognize the statue: everybody failed except Astarion. 2nd time my party M.C. Shield Dwarf Fighter(!), Astarion, Shadowheart, Lae'zel, perception check to recognize the statue: only M.C. and Lae'zel recognized it! Which is real funny because in both case a clerics failed the recognize and in the same time the "absolutely nothing to do with it" characters can recognized it.
Other example M.C. Drow Sorcerer(!) in Underdark failing nearly every second checks (perception and others) but in the next dialogs M.C. can proudly said (conversation option [Drow]) "The Underdark is my home ..." and "This is where I belong ..." (both dialog in Myconid Colony)
So it would be so great and more logical if you flagged/make some of this checks as an "automatic success" for the connecting species/classes etc. because I think even the most riggid and strict G.M. don't force a checking throw to a "Cleric of Kelemvor (or Shar) can recognize a statue of Jergal or not" and "an Underdark Drow can recognize a "Bibberbang" mushroom".... and this ones just some examples from the many similar situations.
I know you wish to implement the "tabletop RPG" experience as correctly as you can, and that's why make every dice throw as an "equally needed" but please be logical in this cases/situations.

Thanks for your time!
Best Regards!
