As an average casual gamer i d strongly suggest to buy the game. I havent seen any of those gamereaking bugs myself and i enjoy the game. There are so many little hidden things that you can play the again and again and keep finding new things. If you are into turn based and into RPG games then go for it with no second thought. You can also go for the DOS 1 if you havent played. Game is similar and it will be cheaper so you ll get a good look on how the game is.
Nice to read you did not encounter gamebraking problems at all. How many hours are you into the game with your current save files?
