It's a shame that a game that was so revolutionary and such good fun to play ten years ago has stagnated to such a damaging degree. It may be a landmark title, but its aged so badly that Perfect Dark's gameplay has become majorly redundant. It's like a favourite toy: well-loved, and good for a quick blast of nostalgia now and again, but nothing else.
Rare have recently announced that they will no longer be revamping any of their older titles. If Perfect Dark's re-release is anything to go by, that may be for the best.
