8. Trusting That Totally Shady Suspicious Dude
There are few video game tropes more irritating than that character who makes only the most minimal effort to disguise their villainy - a fact the protagonist themselves seems completely oblivious to.
"It was me all along!" is one of the moldiest and most played-out twists in all of fiction, and given how few games are written or acted with the finesse of a great movie, TV show, or book, it's fair to say that our heroes often end up looking incredibly silly for not noticing the obvious.
Even in the first Resident Evil, did Albert Wesker - the guy who randomly wanders off and always wears sunglasses, even inside? - not seem completely and utterly suspicious?
What about Kevin Spacey's totally-not-sinister CEO Jonathan Irons in Call of Duty: Advanced Warfare, or Dr. Otto Octavius in Insomniac's Spider-Man? These characters threw up so many red flags, and yet the hero ends up being the last one to get the memo.
Again, this is more of a writing issue than anything, but it nevertheless makes our heroes look like damn fools.
