Highly repetitive and aggravating at parts, but the story hooked me and I played just to see the ending.
Gameplay: Need I say more? Highly repetitve and boring! Bandai needed to rejuvenate the series with each passing game in the .hack series and yet nothing really changed. I'm partly disappointed in this series due to this fact.
Graphics: Average for a PS2 game.
Sound: Repetitive after a while. I want rock in the background or rap or something with the times. Madden and most EA Sports games have this in them. Of course they don't have it in the actually gameplay, but instead in the menu. Bandai could have done this because the main menu is often visited by the gamer playing Quarantine throughout the game. Instead they have gameplay music and techno. I also want to see rock or at least rap in gameplay, but played softer so it doesn't take away from the gameplay. But I can't hold it against .hack in the gameplay at least. On the voiceovers, they're average.
Value: Unless you are hooked with the past 3 games, don't get this game. If you are thinking of trying out .hack, I would advise against it.
