My review is only for Dracula 3: Path of the Dragon. First of all, simply put, the game won't play properly as it comes from GOG. I had to download some extra files. Just check the instructions and link provided here: https://pcgamingwiki.com/wiki/Dracula_3:_The_Path_of_the_Dragon
After doing that, the game run mostly trouble-free (sometimes when it loaded with low fps rate like 8 to 15, I had to reboot the PC and restart the game, then it'd run at 60fps).
Anyway, the game itself is a triumph of story building. Everything is pulling you deeper and deeper. The developers have taken great care to create a fantastic lore, abundant with details, texts, artwork, it really feels alive. Adding bits of historic facts in the mix, made the story even more compelling.
Now the gameplay is your standard early-mid '00s adventure fare. The graphics are quite good for its age, although watch out for the 4:3 ratio...
The puzzles get progressively harder, to the point where unless you're willing to spend dozens of hours slaving over a solution, you'll be using a walkthrough. It's not that the puzzles are necesserily illogical but the sheer volume of information gathered throughout the game, makes it very difficult to find sometimes what is needed for the solution. Unless the game is played non-stop over a few days, you will forget stuff and you will stumble. Also having to do reverse Fibonacci in god damn Latin is not my definition of fun when puzzle solving haha!
In any case, depsite having to resort to a walkthrough a few times the experience is still great. The finale is somewhat disappointing, which is a real shame after spending so many hours and enjoying the journey. That said, despite its few shortcomings the game is still hugely enjoyable.
GOG, just include the needed files for Windows 10 in your installation folder so people can actually play the game without spending hours on the internet looking for a solution or giving up altogether...
