"Ultimately, those most likely to enjoy Front Mission 4 are already Front Mission fans. The best points of the game--the wanzers, their customization, and their ensuing battles--are mitigated by the oftentimes glacial pacing and unnecessary obfuscation of the upgrade system. However, those with a penchant for mechs and a wealth of options for their upkeep--in addition to some patience--will find Front Mission 4 a worthy outlet for their interests."
