Essence of theGeneric Video Game Creepypasta Monster

By drinking this blood red Essence that looks more real than actual blood, you gain the power of a billion-years old entity that for some reason is a fanboy of a specific video game franchise/title of your choice.

• Choose a specific video game franchise/title. After choosing it, you will gain a copy of it a title or a customized fangame. The copy of the game stored in any way you want, from a executable file or ROM, to a CD or cartridge.

• Gain two alternative forms based on the game of your choice. One is the false form, to lure players in a false sense of security while playing. The other is the true form designed to when you finally act and reveal your real face. There is no rule beyond the forms based on the game of your choice, even if only on artstyle, and the true form being unsettling in some way, from bloodstains and red eyes, to a horrifying eldritch monstrosity.

• The game is actually a gateway to a realm you gain upon drinking this essence. Inside your realm, you are de-facto omnipotent inside, but cannot bring anything or anyone created on it to the outside unless under certain circumstances.

• You can design the contents of the game to your heart's wishes, as long as it's related to the franchise/title you had chosen, even if just remotely.

• Once the game is played by a someone you can interact with it either remotely or inside it if you are in your realm, since the game is a gateway to it.

• In any case you can control the contents of the game at will.

• When the player is playing the game, you can choose to execute a challenge to him/her in-game. This challenge's difficulty can be whatever you wish, even impossible, and you can cheat if you want through many means, even causing the sensation of pain to the player in real life, but you can't kill him/her just yet.

• If the player loses the challenge, they are now under your hands, and you can invade the real world temporarily with your true form, through depending on the size it will be scaled down to a average human or the size of the victim.

• This form has god-like physical attributes, can pursue the player using (if any) powers it has inside the game, but it has a limit of five minutes before it wanes and you go back to your realm.

• Even if the player manages somehow to avoid death, after they lose the challenge, you can inflict hallucinations on them that can cause suicide, and after a day your true form can manifest again in whatever location he/she is in to finish the job.

• After the player is killed, his/her soul is unable to pass on to the afterlife and will instead be trapped in your realm, where you can do anything you want to forever.

• Your power increases proportionally to the souls you have sent into the realm, to the point that eventually manifestations in the real world have no limits beyond the size of your form.

• With a certain quantity of souls inside, (that is decided by you, but it must be more than 100) you can finally manifest yourself and anything created by you with full power and once it happens, you gain reality warping abilities alongside stronger versions of abilities you had in the game of your choice, nothing short of a Universe+ entity can stop your onslaught, and you can eventually turn that universe into a part of your realm, with all lives included to increase your potency.

• After a universe is taken, you can send the game to another universe, and you will have to repeat the process you made with the previous one, with all the limits and quantity of souls required, but for each universe assimilated into your realm, all the limits will slowly wane and the would-be challenger needs to be even more powerful, until they are gone completely and you can unleash terror (or something else) in the infinite realities as much as you want.

• Besides those forms, you maintain your original body, with it, you can shapeshift in the bounds of the human form, travel outside your realm, have slightly above peak strength, superhuman senses that won't be overloaded by anything and all defects and illnesses cured, through you can use your shapeshifting to pretend to still have them.

• If your original body is destroyed, your consciousness will go to your realm, and you can return to the outside, but you can't turn into your false or true forms unless the requirements are fullfilled.

• Your existence becomes tied to the realm, that is beyond conventional time and space: Should something be strong enough to defeat you once you manage to invade a universe, you will return to your realm, but you will have to start over the collecting of souls all over again, through the requirement will be somewhat lower.

• This also grants you immunity to more esoteric abilities such as soul erasing, time paradoxes, and the like.

• Optionally, you can have a group of cultists that will hop universe to universe and try to make others play the game. You can make them unconditionally loyal or be attracted to bargains that you can make with them and others.

• Optionally, you can also make any minions you create be able to enter the universe you plan to invade, but they will be in a weaker form and anyone they kill won't have their soul taken to increase your power.

• Optionally, you get a evil plot armor that will make sure more people keep finding the game and decide to play it, even with obvious signs that there is something wrong, no matter how widespread a urban legend about you is. It can be turned on and off at will.
