According to the ESRB, this game contains: Violence
Parents will want to steer little ones away from Armored Core 3. The control scheme requires practice for mastery and it's a bigger curve than most children can handle. Besides that obstacle, there's some number crunching and customization strategy involved that's better aimed at teens. There are no sexual situations, no questionable language and no explicit violence.
Multiplayer Maniacs will flip out when hearing that its now possible to daisy-chain four PlayStation 2s (along with four TVs, four i-Link cables and four copies of the game) for a huge mech melee of the kind never before seen on consoles. You can even add a fifth TV for spectators!
Armored Core Fans will have probably finished the game by the time this review is published, but I'll say that Armored Core 3 has the hands-down best difficulty curve out of the series and is also the most polished. If you're not tired of the same-old, same-old, it's a fine effort.
