Why are people even recommending Baldur's Gate 2? I recently played through the enhanced editions of the franchise, and it was an eye opener to just how awful the forgotten realms lore truly is. I did skip Dragonspear, because everyone panned that as shit. I knew nothing of the games, other than I thought the Baldurs Gate I played in my youth was the second installment and not the first one, as people tend to hype the games up without ever mentioning why.
I didn't know what overhyped meant until I played these games. The dialogue is cringe worthy and the vast majority of characters are two-dimensional extremes [e.g. Overwatch, Anime], they've all got one or two quirks that they constantly talk about. Everyone's beloved minsc? Ha-ha, hamster and I must protect the witch!
Nigh all of the side content was awful in BG1, everything except for walking in Baldurs footsteps and exploring the werewolf isle, because it was the only quest in the game the rewarded the player with a reward in the form of good exposition. And the entirety of the main quest line was forgettable other than the return to candlekeep and then clearing your name.
Baldur's Gate 2 is a weird beast, where the main quest is best ignored and the side content is savoured, but interest fades quickly because -none- of the fucking side content has anything at all to do with the main quest, so what's even the point? But it's also the first game to set up the awful fucking romances that Bioware has become infamous for. And it's never been as shoved down the players throat, as it has in BG2. The 'canon' characters development is questionable, Minsc and Jaheira getting over their losses immediately and replacing their significant companions. Aerie is a tumblr speshul snowflake.
I can't really say much about Throne of Bhaal, other than I liked the ludonarrative of the protagonist dealing with his inner bloodlust, which is reflected in the gameplay, but I'm not a fan of how it's never seen in the dialogue, other than in accusatory form.
All I'm saying is, Baldur's Gate 2 came out in time where most other games had far, far better writing, and it should not be held up as an example of its time. Better to play Arcanum or Fallout. And honestly, it doesn't even hold up to the average casual RPG of the past decade.
