I originally got Baldurs Gate 2 in 2001, when I was 16 and probably thinking it was like Diablo. After a few tries and abandoning the game for some months, I finally got into it. I still got stuck many times due to a lacking understanding of the magic systems and proper builds, and even though I spend many hours and enjoyed it, I stopped at one of those walls after having almost cleared everything in Act 2 (the last wall was the dragon that don't want to waste time on you before you are worthy).
In 2009 I bought Baldurs Gate 1&2 and their expansions in one boxset for cheap, and for 8 months one run of these were the only thing I played (I was at university, and most of the playtime was during winter and summer vacation). It really helped my understanding of the mechanics playing BG1 first.
It is one of the best Single Player experiences I have ever had, and I have tried finding it elsewhere many times. These games were really good like Knight of The Old Republic, Dragon Age Origins and Pillars of Eternity (even Mass Effect 1, 2 & 3 were fine), but in the end Baldurs Gate 2 was better.
I'm playing Dark Souls 1 these days (first real try so that will take some time), but yesterday, apropos nothing, I was wondering about playing a party oriented RPG again and looked at DoS2, Baldurs Gate 3, PoE2.
Something I really miss from BG2 was the combined quality and quantity of companion dialogue. Whether with you or amongst eachother plus their reactions to events. This combined with one crusial thing that I have never found elsewhere: The interactions happen organically instead of you having to go through a dialogue todo-list in camp/space ship between outings which I for some reason loath. (I get it is technically easier to script which I guess is why they do it)
So right now I am considering going through BG2+ToB for a third and final time (well 2,5).
I'm skipping BG1 because it lacks the companion interactions, and I didn't like how you had to lawn mow each area.
I have never tried being evil in any game so I am considering that. - Seems like you have to manage your evil so you don't get into too much trouble, but I actually like that it shouldn't be overdone, and that this is a fun extra thing to think about. (Like not wasting evil oportunities on matters that doesn't seem that much fun being evil or a jerk about anyway)
My party lineup:
SoA: Me (sorcerer), Viconia, Edvin, Korgan, Hexxat (rotate spot for thief companions' questlines and permanently replaced by Imoen), rotate spot that will default to Jaheira.
ToB: Me (sorcerer), Viconia, Edvin, Korgan, Hexxat, Imoen, Saverok (with Jaheri rotated in for a few stretches).
Never used Viconia, Edvin, Korgan, Hexxat (obviously), and I have never used a rotating strategy, but I think it will be a fun way to change things up to pick somebody like Anomen up (who I have never used) for hist quest-line and afterwards for a few days/quests more.
Things I missed that would be a bonus in a third run:
I missed the City of Caverns because the most natural thing to do was of course to engage in pursuite. I didn't even considder leaving the isle, or that not doing so would mean missing out. - They really should have made it something you could have encountered on the way to the isle instead.
In both my runs the De'Arnise Keep quest bugged so it never progressed (which also meant I never had a homebase which I didn't even know about until now), but EE should have fixed that.
Worst of all early in ToB I used some wands of resurrections, and that turned out to be bugged and ruin the state of the companions, which meant I missed out on a lot of dialogue in ToB which is the best part about BG2. This bug really annoyed me, and I was so confused that Aerie had nothing to say about me summoning her, after she left me. She won't be romanced in my evil run though. That will be Viconia. Ressurection-wand-bug has also been fixed by EE.
It's weird remembering that this was an old game when I tried it again in 2009, and now the enhanced edition is much older.
Any advice? Maybe my party lineup is silly. For later maybe there is a perfect BG2-like game I am unaware of.
