For parents, I don't think I'd recommend Front Mission 3 to anyone under the age of 14 (especially if they prefer quick action games and don't care for the techno-thriller plot). Not only does the game make very mature overtures about war and politics, but the story does get to be very long and convoluted. Also worth noting for all is that this is one heck of a long game. The back of the CD case brags that it provides 150 hours of gameplay in order to complete both senarios (which are surprisingly different in terms of plot and characters). I, for the most part, concur with that timing.
Hardcore strategy fans are going to find the weak enemy AI (artificial intelligence) and loose tactical elements in Front Mission 3 to be a little too "lite." Though there are ample oppuntunities at making personal configurations and modifications to a players team of Wanzers.
Role-playing game (RPG) fans and more casual gamers will be more at home with the less mentally intensive approach to battles and the long-winded epic sweeping oh-so RPGish storyline.
