This has led to various popular fan theories developing for certain games, with the following ones being the most notable of the bunch. Not only do these theories make a ton of sense given the events of the game, but many people would argue that they actually lend to the overall quality of the story as well!

8 The Indoctrination Theory (Mass Effect 3)

Mass Effect 3 is one of the most divisive games ever made, mainly due to its ending. People felt that the game didn’t take their choices into account, with the endings feeling pretty lazy and not providing any sort of closure either.

This has led many people to believe the theory that Shepard was indoctrinated at some point in the trilogy, leading to the fever dream that is the ending. It’s a riveting theory that places Shepard’s actions in a new light.

7 The Player Character Is Repenting In Hell For Killing His Sister (Limbo)

Limbo is Playdead’s first game that ended up being a wild and engaging adventure in its own right. A platformer that could get extremely dark at times, the story of Limbo is kept vague on purpose so that most players don’t figure out what’s happening until the very end.

The inclusion of the main character’s sister in the game and the mysterious nature of her appearance have led many people to believe that the protagonist is in hell and paying for the crime of killing his own sister. This is why the game’s deaths are so gruesome and the adventure keeps on looping after the end.

6 Squall Is Dead (Final Fantasy 8)

Squall is a protagonist that many people have pretty mixed opinions about. Some people find his personality to be quite edgy, while others understand where he comes from with his aloof nature.

Regardless, the fan theory surrounding his supposed death at the hands of Edea is pretty riveting regardless. After getting pierced by her icicle, Squall comes back with little to no injuries as the story slowly becomes more dreamlike and over-the-top. This has led many players to believe that the story following this assault on Squall is a dream, with the protagonist being dead all along!

5 The Entire Game Is A Simulation (Metal Gear Solid 3)

Metal Gear Solid 2 featured two major twists, mainly centering around Raiden being the main protagonist and the entire game being a simulation. The latter development took so many players by surprise that other games in the series have also been scrutinized for the same!

Such is the case with Metal Gear Solid 3, where many events point towards the game also being a simulation in its own way. Naked Snake mistook the term Virtuous Mission for Virtual Mission, while the game also ends when the players create a time paradox as well! These small instances point towards the fact that maybe the events of the game are just being experienced once again in the future.

4 The Game Takes Place After A War (Pokemon)

One thing that players will notice in Pokemon is that adult males are in pretty short supply. Most characters are either aged men or growing children like the protagonist themselves.

This, coupled with the incessant need to make domesticated monsters battle, hit towards the fact that the world has gone through a severe war, with Pokemon battles being a way for everyone to compromise on wanting to initiate conflict. It’s a pretty out-of-the-box yet engaging fan theory that has gained a ton of traction.

3 Giygas Is Actually A Fetus (Earthbound)

The final fight against Giygas is one of the most memorable boss battles in video gaming. Ness and his party members need to throw everything but the kitchen sink into this battle if they wish to stand the slightest chance of victory.

Players need to travel into the past to fight Giygas, where they need to travel through the Cave of the Past that almost resembles a birth canal in a twisted way. This, coupled with Giygas’ infantile cries and unique look, has led many players to believe that this boss is actually a fetus when fought by the main party.

2 G-Man Is An Alien (Half-Life)

G-Man is one of the most mysterious characters in the Half-Life universe. He’s almost like an omnipotent being that is surveying the player from afar and always plays a role in the events that shape the adventures of Gordon Freeman and other important characters in the series.

While many people assume that he’s a government agent, this fan theory takes a wildly different take instead. It discusses the probability of the G-Man being an alien who is surveying Earth and manipulating events for his own amusement.

1 Chara Was The Narrator All Along (Undertale)

Undertale is one of the greatest indie games ever made, with its writing being full to the brim with charm. It’s also a game that can take a pretty dark turn if players decide to follow the Genocide route.

This reveals the presence of Chara, the first human to fall into the realm of monsters who caused untold death and destruction during their time there. Most people believe that the narrator — who has shown their own sentience several times — is actually Chara themself, which is a pretty mind-blowing theory indeed.
