These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ensemble Darkhorse: Cain is easily among the most popular characters of the game going by online comments.
Genius Bonus: Gun-savvy people who read the data files can trace the inspirations behind the weapons:
As an example, Faye's R93 sniper rifle looks like a Barret M82, but has the design history of the Blaser R93.
The Akagi 74 is essentially the AK-74 with a longer barrel and carrying handle.
When fully upgraded, Dan's assault rifle is essentially an light machine gun; this makes sense when one realizes that it's based off the HK416, which formed the basis of the USMC's M27 Infantry Automatic Rifle: an extremely accurate LMG in assault rifle body.
Porting Disaster: Averted. The PC port plays well, flows smoothly, graphics look as good as the 360/PS3 (with an Nvidia GTX460), and most importantly, QTE prompts can be set to display as either 360 gamepad or keyboard.
Strawman Has a Point: It seems unfair to issue termination orders for all Hollow Children, but Yoshiki demonstrates that they can be overidden at any time, and the Chairman of the Joint Chiefs of Staff is a Hollow Child. A Hollow Child is the ultimate Manchurian Agent, able to infiltrate anywhere.
