There's little I can say that hasn't already been said. It's a great game, not perfect, not the best ever made, but definitely one with a very distinct mood and personality, fun gameplay, and surprising emotional depth and immersion despite its relative simplicity and short length. It definitely deserves a sequel (and the ending begs for one), and luckily it looks like that may finally happen- it's been rumored to be in development since 2008 but, unlike most vaporware, it seems to have making steady progress year by year- by all appearances it's actually coming along and news is being released about it on a regular basis... it's just taking a really, really, really long time to come to fruition.
A few cons: The GOG version has flickering problems, especially on the loading screens and item box, which persisted to a small degree even after I performed the recommended fixes. It wasn't enough to mess with the gameplay, but was an annoying distraction. The camera angles, though probably no worse than other games of the era, were also irritatingly uncooperative, especially when driving the hovercraft or fighting large groups of enemies. And damn, that race announcer is really obnoxious.
Pros: Too many to list, but one in particular is a surprisingly scary and menacing final boss that stands out from the generally cartoony style of the other characters. The villains' motivations are never really explained, but the mystery of their origins and connection to Jade are a high point of the game, and the final stages add a lot of creepiness and danger that was generally lacking in the authoritarian but bumbling enemies of the planetside stages. Another pro would be the extensive use of the camera, as everything from an item identifier to a "look mode" to a decoder to a, well, camera. It almost functions as its own character, and I liked the emphasis on journalism and the consequences of Jade's photographic espionage.
