The game has a noticeable memory leak and tends to crash after running for a longer time. Also the quests difficulty rating can be noticeably different from their actual difficulty. The spells cannot be learned anymore from grimoires which is quite a disappointment. The story seems fine, but there's bit too much politics for my taste and I never liked companions approval system in any game that has it, this one being no exception.
The main campaign as well as some DLCs (Witch Hunt, Leliana's Song) are great, Awakening expansion is a bit more tedious and pestered by quest-breaking bugs, but it's still bearable enough to get through to the end. The entire game crashes terribly even in the ultimate edition, for no apparent reason. It has enough RAM and disk space, it is on SSD C: drive, it's not overheating - and it goes boom at every possible occasion anyway. It probably is some memory leak since after some time from launching some textures go visibly missing in some areas. And Golems of Amgarrak are the best example of how not to make DLCs, ever. If I were to evaluate just this DLC it would be with 0 points, as it has nothing but badly scaled difficulty level. No story worth mentioning, no interesting companions (the highlight of e.g. Witch Hunt), virtually nothing.
What can I say, I love this series and BG2 is a definite improvement over BG1 in terms of companions (although I do grieve some could not be carried over from BG1) and even, to some extent, in terms of the main story.
After playing through the main campaign, Shadows of Udrentide and half way through Hordes of the Underdark I was evaluating the game as 4 stars. The henchmen system is not the best and a bit sad after running with full party in other DnD games like Baldur's Gate or Icewind Dale, the inventory management is very sad, but the game was keeping a certain balance between its difficulty and character level. However, at the end of chapter 2 of HotU this went crumbling down and kept getting worse to the end of DLC (same as inventory management issues), which ruined the rest of the gameplay for me. Moreover, I love magic classes and this game seems to hate them, making certain bosses straight immune to spells, so your magic user character ends up as a cheerleader rooting for your henchmen/familiar/summons as they take them down... how epic... not.
It was a pretty decent game, although I had to get used to a completely new UI, combat and team systems (I was expecting something more in line with BG), until I reached the final boss which turned out unbeatable because apparently it's such a great idea to increase the boss difficulty like 100x times as compared to all previous encounters. This is when you know that the programing is really bad. I regret ever purchasing this.
