Goblins would be an intersting take but would need a change in the first encounter since you probably help the attackers rather than defend the Druids.

Genasi, obviously
If we get genasi, Dragonborn is a must since they both came with Abeir.

Races i would love to see:

Tabaxi
Leonin (yes i like cats)
Aasimar
Half-orcs, not even that unusual
Kenku
Warforged (Eberron might be a bit far fetched though)

There are tons of other cool races but i guess even this is too much laugh

I always hoped someone would make a MMORPG of faerun. No something like Neverwinter but a real one where you can actually play. Sadly i only have ideas but no money or skills for something like that :P
