Overall opinion:
It's promising, however, one thing is clear - this is not Baldur's Gate 3. Nor is it Divinity: Original Sin 3, as some people like to troll. It's something new, and I wish this didn't try to ride the hype train of calling itself what it isn't. But at least it is a good game, past all the issues. After EA ends and it releases out proper, I've no doubt this will be a great game and I will play it - but I am certain there's not a speck of nostalgia in this and for this I am sad.
I quite agree. The game in itself seems to live up to its promises and I really like what I've seen so far. However, a recognizable tune here and there (does anyone remember that sound when a weapon was identified in BG2?) or a (more elegant and somewhat smoother) user interface that graphically reminds you at least a bit of BG2 (i did like the "rest" icon :-)) would really tickle that nostalgia nerve of those like me who have waited for this for roughly 20 years.
