Visually, the game doesn't age all too well. The title uses the now regularly seen 360 degree wrap-around style for making an adventure game first-person, and while this was fairly new back in 1999, it will surly feel dated to any newer gamers who will be picking this title up for the first time.
Then again, adventure titles aren't really about the visual, and when looked at in the context of 1999, Amerzone looks pretty good. Besides the slightly-warped scenery, the interactive objects like characters seem a bit blocky or blurry by today's standards, but are also pulled off relatively well by the mobile device's processor. The details that really sold the game's age though were the people, most notably, the old explorer you meet. While the character is some 70 years-old, the extra 12 years since the game's first publishing have not been kind to him.
Sound has held up well though. Much like its original version, Amerzone: Part 1 is filled with ambient noises to help sell the scenery and voice-acting is good enough to convey the emotion and feel of the conversations. I really enjoyed some of the details in the game's sound effects like the dipping noises you hear while exploring an underground tunnel in the old man's lighthouse.
