With how little map there is, it cant feel like a BG game, yet. BG is all about choices, big world, many characters, many quests. EA will never feel like that as it's not the finished game.
If all the maps have as much diversity in zones and NPCs and things to do as the EA then, the game will definitely BG. I also have a feeling the illusion in our heads will turn out to be a god trying to come back to life in someway, which will tie the plot into BG too.
