I have play previews Armored Core games and they were good but this game has taken everything to the next level with fun gameplay, great graphics, sound, online and just about everything. I have play this game for countless of hours and its fun. don't let other poor reviews given by other sites stop you from buying this game. most of my hours i spend in this game was customization, just making the Mech appearance is just awesome. if you haven't play previews armored core game i suggest you start with this one and you won't regret it one bit.
