Just got to the Underdark in BG2EE about 70 hours in. BG2EE looks dated but ohhhh boy it blows DOS2 out of the water in depth, tactics during combat and just ways to break the game..
Also the amount of different ways to complete a quest is also superior to DOS2.
BG3 has to be RTwP, TB is archaic and the battles drag out far too long and offer zero realism and are no way near as entertaining.
To the guy that said BG2 is just about pre buffing your party and clicking on the enemy! Stop playing on easy difficulty on story mode! In reality your party wouldn't last 5 seconds against a caster with a few mobs.
