I think Larian could have pulled this off, even with their DoS system tweaked to D&D rules more or less but, they haven't managed to bring any of the aesthetic from BG.

1. Similar menu, tabs, interface would go a long way to make it feel like home.
2. I miss the little green circle around my feet
3. The way characters emote when you click on them "STOP TOUCHING ME!"
4. The little things

I think they forgot one simple rule, K.I.S.S.
