And I think being able to go through without being murder-hobos is a great thing for an RPG, and something I missed in BG1/2.
Will be interesting how they are going to balance xp that way. Also slightly hopes that BG3 won't be as strictly level-gated as DOS is. Also, playing a rogue may for once be super awesome.
Outside of combat-heavy dungeon crawls and the like, I've oft been annoyed that NPCs would just aggro on you the moment they set sight on you. That makes sense depending on the NPC (party is caught traveling by a bunch of crazies or is attacked by wild beast), but else it's oft wasted potential.
Casually replaying BG2 on and off for a couple weeks already, and I've only now realized how much of a dungeon crawl/combat heavy game this was in general, in particular the middle section. Throne Of Bhaal I didn't rate very highly back then (and I like Icewind Dale).
This may be very un-BG-like, but sounds all the more advanced for it.
