Whatever is the title, this could be a good game and then an even better can follow.
This game won't be a "3" following BG 1 or 2, too many things have changed since. Trying to clone that after so long time, by completely different people, while just changing a few variables here and there (to keep it alike), would lead to a worse game than having the freedom to innovate and create a completely new version, keeping only those parts & references which can still fit here.
The Game of Thrones changed so much after season 1& 2, and less time have passed. Star Wars the same, and not a single game or movie could keep up with an initial "legendary" success, if that happened at initial parts. First Love happens once in a lifetime, never ever again. There is still joy after, but never the same. Good games are still made, and the new generation will start with these, and fall in love, like those old ones never existed.
