I think people are giving this game too much credit. Not all old games were great, and I think this might be one of those games that never was and still is pretty mediocre. Not to be a wet blanket, but with all the hard ons that people are having for this quite unspectacular game, I just had to inject some objective criticisms.
Unbalanced weapons, bloated arsenal, unnecessary gameplay features such as the vehicle mode, questionable game mechanics decisions like not being able to holster my gun while in a non-combatant area were a few of the issues that I noticed during my hour or so of play. I could go on about the low poly characters and low res textures, but the dated graphics are forgiveable considering the game's age. However glitches during cutscenes that allowed me to shoot NPCs while having to wait for them to finish their speech before turning and popping a cap in my head, not so forgiveable. Speaking of which the voice acting was surprisingly tolerable in a camp value kind of way.
Perhaps I'm being a little harsh but the whole time I was playing felt like an enthusiastic anime mech fanboy's mod project that never got out of beta testing. Interesting ideas and concept that were unfortunately never fully realized for it to be a successful commercial project.
