What was one "loophole" you used to exploit in a game to get ahead?

My Sims character didn't have a job. Instead she would spend her time seducing Sims from other households that periodically walked past hers. Sim relationships progress pretty quickly, so it wasn't hard to get them to agree to move in after working my way through the romance interaction tree. And when someone moves in from another household, they bring $20,000 with them. Once I had the money, I'd kill the guy with fire and sell the tombstone for an additional $3. Rinse and repeat. Then spend the money designing a ridiculous mega-mansion. I miss that game.

In Skyrim (and Fallout 3 & 4 I think), you can pick up any owned object and hold it out in front of you, then walk out of the room, hide, and put it in your inventory. Nobody notices you stealing. Basically allows you to steal anything so long as there is a secluded place you can go. Very useful for cleaning out the Arch Mage's Quarters with all of its respawning grand soul gems, rare ingredients, and large coin purses.

In the Playstation1 game Star Wars: Phantom Menace (level 3) there was a short cut scene where a tank shoots a missile at a bridge and the bridge is destroyed, so you have to go through the entire city of Naboo to get to the palace. But, if you open the disc tray before the bridge is destroyed, the missile won't do any damage. So, you close the disc tray and walk over the bridge and complete the level straight away.

Just before the last fight in Batman: Arkham Asylum, you're in a room with 10-12 enemies who stand still until you throw the first punch. I lined the floor with spray-on explosive and detonated it as 'the first punch', killing everyone.

I used to jump off the Power mat in NES Track and Field and jump back on to achieve incredibly long jumps.

I always play a lot of backgammon in Yahoo Games - and some guys were real jerks when losing. Generally they'd stop the game by taking the maximum 10 minutes for every move, hoping I'd quit. I learned a way to boot these people off Yahoo for as long as I desired, by trying to log into their account. When I used the wrong password ten times, the account was locked for 24 hours. They couldn't log in again until I chose to permit it.

In Skyrim there's the infinite levels trick. I can't remember exactly, but it had something to do with putting a special book in a bookshelf and then re-reading it for a level every time. Also hitting the old monks on the mountain from stealth to quickly gain stealth levels.

In dead island if you kick the zombies into the water, it does constant damage while its hard for them to get up. Id always lure them there then fuck em up.

You can, with good timing, use the werewolf transformation in Skyrim to stack multiple equipped Amulets of Talos to give yourself 100% shout cooldown time reduction, at which point the game just gets nuts. No idea if that’s been patched up in the later re-releases or not, but stacking a bunch of Slow Time shouts and Whirlwind Sprints basically makes you The Flash, and endless Soul Tears, Fire Breaths, or Unrelenting Forces makes any and all combat pointless. Stacking a bunch of Slow Times and Storm Calls is where it’s at, though.

In Zoo Tycoon, which I played obsessively back in the day, you could hit shift+4 to get an instant $500. If you held it down, it was basically an endless supply of free money. The thing was, it would degrade your fences so the animals in your exhibits would escape, so I'd do it whenever I started a new game before building anything.

In Fallout 4 (maybe for other games in the series as well, haven't tested it) your companion usually has a carry weight and you will not be able to transfer items into their inventory after that limit is reached. However if you drop an item and direct them (using the command function) to pick it up, they will be able to infinitely pick things up no matter the weight. After finding this exploit, hoarding took upon a new meaning.

On NBA Showdown (EA Sports basketball game from like 1993ish), if you played with the Charlotte Hornets and did a certain dunk with Alonzo Mourning, you could almost get unlimited points. Mourning had a double pump dunk that missed about 80% of the time. However, the points still counted. You could miss the dunk, rebound, miss the dunk, rebound, etc until you eventually made the dunk. You could get 10 points on one possession.

When Forza Horizon 3 was just released, you could pay 50k to perform a slot wheel spin. There were a few Horizon edition cars you could win. I calculated that you would get one around every 54 wheelspins. Thing was if you already owned the car, you could choose to receive 5 million in cash instead. Left the game with an auto clicker overnight. By morning, I had enough to buy and upgrade every car in the game. Don't know if the ability to do that was intended, but it's now patched.

Warcraft 3 campaign final mission. Used Hippogryph Riders to kill the Undead acolytes that construct the base once they take over the human base. If you kill all 3 before the necropolis finishes summoning, they don't build any more and you just wait out the ~40 minutes to the end of the mission.
