I would recommend you not to read too much about the game. Play the demo first, it's a good representation.
If you, after completing the demo find the game interesting and, want to continue your experience I would suggest that you back up your saves, before the purchase, because Steam will just delete it all upon installation of the full game.
I was a bit sceptical about the game at first, especially in regards to the new boy'ish look of Gabriel Knight and this silly southern voice that is being used, but also in regard to the changes of design. It took me awhile to get past that change and I was just barely ahead of it at the end of the demo.
Truth be told I was never really a fan of the GK series even though I tried my hand with all them in their own time with a declining interest, that was completely gone after five minutes with GK3. I generally despised the Sierra Adventure games, because they were so dull, traditionally old-school and unforgiving somehow compared to the humorous and creative Lucasarts Adventure games I loved.
I am glad to see that Pinkerton Studios have gotten a much better hold on the game engine that severely scarred the previous Mobius game. Gone are the wandering eyes and jittery animations.. There is still a few minor flaws, but much less than before. There is also lip-syncing and it works surprisingly well.
I read quite a lot of reviews about the game, the good, bad and ugly, because I was a bit lukewarm about GK, but I was curious and played the demo first and even though this new version isn't quite the same high-caliber version as the original it's not a bad game, not a bad game at all, but it's clearly not a total remastery of the old game, since they've changed the voice actors. Even though I was quite resentful of the voice of Gabriel Knight in the beginning it kind of grew on me and the accent is also more downplayed as the game goes on. The rest of the voice cast is pretty decent.
My only real complaint about the game is the background Music - it's bloody horrible and totally out of place with the spirit of the game unlike the game music during cutscenes which is very well done. I was about ready to quit before the demo even got started, because of it, but I hit a key to skip the intro credits and turn off the music, which saved the day.
There is a new hint system in the game, but unfortunately it's neither very intelligent nor progress based. The few times I needed it I was way ahead of the hint system and had to wait for the hints to catch up to my point of progress, because of build-in timer, that I assume has been put in place to avoid that you spoil yourself too much and even then it was extremely rare that it was useful at all. At one point it was completely useless and I had to Google for a solution, because I got a bit ahead of myself and was unable to pick up on a vital clue on how to unlock an important puzzle.
There were times when I was a bit lost about my next move, because the game is a bit short of a narrative and there is a certain amount of things that you need to solve before the day ends, which isn't very clear, but the first hint of each day usually give you a list of to-do's of the day. I do not recommend using the hint system at all, because the game is actually quite short.
I saw a reviewer complaining about the same animations being played every time you leave an area, but that's kind of a silly point, because you can use fast-travel everywhere. You don't have to leave any area by going to an exit point at all, because you can bring up the map at any point, which is really nice, but unfortunately Gabriel Knights current location isn't highlighted on the map at all.. Sometimes I went to places where I was already.. The same teleportation system in Mobius has transferred to GK1 as well, but there are times when you need someone to follow you that it backfires.
There is still a bit of the old ghost of Sierra's unforgiving gameplay present, but the good news is that there has been added a RETRY option for those special events.
I finished the game in 15 hours and I am actually a bit surprised that I had a such a good time with it. Jane Jensen was a much better writer twenty years ago, but she also had a co-writer on GK1, and that part still stands.
