First the bad:

the legend of the fox in the wolf dragoons

Mechwarrior/Battletech (MW/BT) and Naruto
SPaG abuse, Naruto is related to a canon from the games, messing up weapon tonnages, (2 LRM-20s+a Gauss Rifle on a Vulture? As if.) weapon uses, (LRMs fire in flights of 5, not single missiles.) calling the WoB fascists, (They're religious zealots.) and mixing Clan and spheroid names. If I can get a Naruto fan to cowrite with, this'll be my first mission.

The good:

Hunted Tribes:

MW/BT+ nBattlestar Galactica

The fic gives a point of deviance from canon, makes references to canon past the point, explains stuff with the relevant links, and has few SPaG errors. Financing a war is important, damage matters, public opinion is important, the fic keeps everything as realistic as possible for the settings.
