I started Amerzone yesterday morning and finished it just before midnight last night (had a few breaks during the game). Visually, musically and even narratively, I found this game to be one of the most enjoyable I've played. It is short, some say too short, but I even enjoyed the fact that I didn't have to play it over several sittings.
The puzzles and obstacles you have to figure out all fit in with the story and none of them were so outlandish that you can't see the relationship of what you have in inventory versus the task at hand. I also liked the fact that after you finish a chapter, the inventory items not needed going forward are deleted automatically. Many a time I've had to sift through old items that were not going to be used any longer just to get to the correct item. There is wonderfully written WT linked on this site but the game is not too difficult even without the WT. I only had to refer to the WT twice for hints, never for constant referencing.
This is a game produced with high quality not only in the visual and auditory sense, it also played without a single glitch on my Windows 2000 Professional OS. I can't say that about hardly any game these days, even those written for Win2000!
Like my copies of Myst and Riven, I'm going to keep this game. When I want to enjoy a wonderful but quick adventure game, I'll now have Amerzone to re-explore. I really hope that Microid's Siberia carries on the quality level I've experienced in Amerzone. From the looks of the excellent screen shots, it sure seems like they will.
