In Airship, when facing against the Right Hand Man, regardless of what battle style you choose (Final Fantasy or Earthbound), you win if you choose the items/goods option. This is appropriate, since throughout his escapades, Henry's only been good at using items and gadgets.
In Complex, Markiplier and Jacksepticeye make cameos as prisoners. This makes sense when you remember that they've played the games before, and thus, they've helped Henry pull off his crimes!
Obtaining the "Presumed Dead" ending in Complex requires you to let the decision timer run out, something that has always meant certain death up until this point. The "presumed" part could refer to the player just as easily as the complex staff.
In Airship if you choose to steal the ruby crystal, the Tophat-clan and the government eventually face off in the desert. However, a building near the battle sees this and puts one of 4 discs into a machine. All but one kills Henry, and sometimes the world. This would be less terrifying if the guard wasn't INSERTING DISCS AT RANDOM, which means that the people in charge of the deadliest weapons in the world don't know what they are or what they do
Also compounded by the fact that the goverment didn't know what was there, implying that a random company has more advanced tech than the government.
