They are absolutely lovely, though undeniably very old school. BG1 is more action-adventurey with a bigger emphasis on exploration, BG2 is very story-heavy. They have aged remarkably well, considering they're over 20 years old. The handpainted backgrounds still look pretty.
With potential increased interest due to BG3, I wonder if it would be an idea to create a community for the classic Baldur's Gates 🤔
