Top 10 Most Amazingly Overpowered Gameplay Mechanics in Video Games

Please note: This list does not include things such as weapons and glitches.

1. Flying - Kirby

   In other words, Kirby can fly right over quite nearly all of the enemies and levels of his games.

2. New Game Plus - Chrono Trigger

   As if this game's combat isn't already completely too easy in normal playthroughs of it, New Game Plus allows you to have completely over-leveled characters 100% of the time.

3. Parrying - Street Fighter III: Third Strike

   Basically, this mechanic is a "Super Block" that is more difficult than normal blocking. If the Street Fighter franchise was more realistic and balanced than it actually is, then this mechanic probably would simply reduce the amount of chip damage that blocking attacks causes. However, since the Street Fighter franchise is as utterly cartoonish and nonsensical as it is, this mechanic causes EVERY attack that it gets used on to deal EXACTLY zero points of damage (most notably projectile attacks, which it causes to become almost completely useless).

   This mechanic thankfully was (mostly) scrapped in Street Fighter 4 and Street Fighter 5 in order to prevent Ryu's infamous Hadoken spamming and the like from becoming completely obsolete, but human error is one of THE only things that prevent it from making Third Strike's characters completely invincible.

4. Combat System - Undertale

   Proper Pacifism: Allows you to beat the entire game by basically just running away from its enemies.

   Partial Pacifism: Is an even more ridiculously easy version of Proper Pacifism.

   Genocide: Allows you to effortlessly one-hit-kill quite nearly ALL of the game's BOSSES.

   Frisk Being Able To Dodge Attacks: Can very easily make him/her quite nearly invincible.

5. Super Punching - Super Punch-Out!! (SNES)

   It deals ABSURDLY large amounts of damage to Mac's opponents and can be used an infinite number of times as long as you keep Mac's power meter full by not allowing him to get hit by his opponents.

6. Magic - The Elder Scrolls V: Skyrim

   Healing: Can give its users nearly infinite amounts of health.

   Impact: Can very easily be used as a stun-locker (not only on enemies, but also on BOSSES).

   Destruction: Basically is an elemental bow that has unlimited arrows.

   Conjuration: Summons "helper" characters (which generally are extremely OP in modern Fallout/ES games).

   Mind Control: Can make enemies unable to attack you.

7. Whip Aiming - Super Castlevania IV

   If you haven't played or seen Super Castlevania IV and think that its combat is going to require the type of strategic prowess that the combat of Castlevania 1 and Castlevania III (Dracula's Curse) requires, then you definitely should think again.

   This game's version of Simon's whip makes this game's sub-weapons almost completely pointless due to the fact that it can be swung up, forward, down, and diagonally. It deals almost comically large amounts of damage to both enemies and bosses, and even passes straight through walls and the like.

8. Attack Dodging - Mario & Luigi

   It causes the attacks that it gets used on to deal EXACTLY zero points of damage to Mario and Luigi themselves and is RIDICULOUSLY easy to do in most of the sub-franchise's cases.

9. Wall Jumping - Super Metroid

   While the designers of Metroid Fusion at least had the common sense to make this mechanic somewhat realistic so that it wouldn't allow Samus to simply climb straight up a single wall rather than properly jumping back and forth between two walls, the designers of Super Metroid far too clearly did not.

   Due to how incredibly broken its physics are, Super Metroid's version of Wall Jumping allows Samus to rather easily:

   - Use quite literally ANYTHING that is solid and doesn't cause contact damage as a platform for it.

   - Collect the Spazer Beam without having the Hi-Jump Boots.

   - Collect her first Power Bomb Tank before defeating Kraid or entering Norfair.

   - Replace the Grappling Beam with it in far too many cases.

   - Perform absurdly difficult-looking Mid-Air Morphing stunts.

   - Replace the Space Jump with it in far too many cases.

   - Collect the Speed Booster and the Wave Beam far more quickly than the game wants her to.

   - Not actually need Space Jump when fighting Ridley 2.

   - Complete the game's Wall Jumping tutorial by not actually doing what she is supposed to do in it.

   - Avoid the Golden Torizo's Laser Spam attack without going behind it or having Space Jump.

10. Dodging/Blocking System - Super Smash Bros.

The Contenders

13. Throwing Things With the Gravity Gun - Half-Life 2

14. Using Bottle Rockets and the Heavy Bazooka During Battles - EarthBound

15. "Realistic" HP System - EarthBound

    While this mechanic generally is completely useless during the early parts of EarthBound, it becomes EXTREMELY broken during the late parts of EarthBound. Basically, this mechanic causes attacks that would instantly kill your party members in normal role-playing games to barely do anything to your party members as long as you can heal them or win the fights that "mortal damage" gets dealt to them during quickly enough.
