The OP is delusional to think Larian will create an expansive game like BG1. Just play DOS2 and you will be quickly disappointed. They lock you out of prior places, the respective huge maps of each Act feel repetitive and restricted and the world is sterile. They even lock your companions after Act 1.
The expansiveness and low stakes beginning are the only things BG1 does better than BG2. The rest, there is no comparison.
