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.
YMMV: Assist Me
Growing the Beard: Both in the literal sense and from a production standpoint. When the series started, Max was clean-shaven whereas presently he sports a goatee. The production quality has also increased over time (most notable with elements like Doom's costume; in the older videos, Doom looks more like some dressed up as Doom with a quickly thrown together outfit. Now, he looks much cleaner and more like the character), with the Ultimate Assist Me series even getting help from Capcom itself.
Hilarious in Hindsight: One of the lines in the Rap Battle between Doom and Wesker has Wesker attacking the fact that he was in Top 8 at EVO 2011, while Doom wasn't. Cut to EVO 2012, and it's Doom that makes it to Top 8, while Wesker is notably absent.
One of Max's videos has one of Doom's (fake) taunts giving a Take That to Roll. Months later, this happens.
Max seems to be a fountain of these, and often says things during his lets plays of other games, such as "Take to the skies!" (used for jumping attacks), "I play fighting games!" (used when he plays non-fighting games and does some cool melee combos), and of course "Yo video games!"
R-R-R-R-R-RAGEQUITTER! Taken from the very first episode of The Online Warrior for Injustice: Gods Among Us when he plays Batman (in his Batman Beyond costume) and an Ares player, well, ragequits on himójust as the match is about to end in Max's favor! The fact that a bug in the netcode resulted in Max getting the loss and the Ares player getting the win instead of the other way around didn't help matters either.
Never Live It Down: Out of all the characters featured in Assist Me, Doom is the only one to actually beat Max in Marvel and always brags about it should he be given the chance.
One-Scene Wonder: Morrigan appears for all of 15 seconds in Retro Assist Me as a, er, assistant of Commando's. Some people will attest that the only reason they watched that video was to see her.
Pandering to the Base: The most probable reason why Dante and Morrigan will make an appearance as official guests in the Final Season.
What an Idiot: Really, any normal person, let alone someone with Doctor Doom's intellect, should have enough common sense to know that shooting pure concentrated plasma will not only do nothing to stop a fire, it would only make it worse.
