What games do you think are unintentionally easy to break in terms of leveling and game mechanics?

Having to rubberband my controller while going to work to walk continously into a wall to get 100 sneak in TES Morrowind

-saints row 1's hitman
with a few hours to spare (took me just about 2 hours with a little taxi glitch) you can become mega OP right after the first mission. i mean, you never have to pay for ammo ever again, your weapons (especially the plat urban) plow thru enemies, what's not to love?

-saints row 1's titan
yes, another one. store a titan in your garage, go to rimjobs (the mechanic) and using the aformentioned weapons, get the titan from your garage, despawn the wreck (by talking to the mechanic), collect your cash, talk to him again, and choose the titan BEFORE it's shown in the garage. that way, it's always one shot. i used this to get a million in like an hour.

-dark souls' minmax strat
SOOOOLLL LEVEL NINETY NINE
jokes aside, you can use a smaller giant dad build (at only level 15) early game to plow scrbs in pvp

tony hawk underground 2's nonexistent oob boundaries
-in some maps you can glitch into the void, being stuck in the air doing whatever tricks you want. eventually you get a gajillion points! VERY fun to stall lobbies in thugpro ;)

Throwing my opinion in with the folks saying FF8.

Using card conversion and functioning toy can make your OP as fuck almost out of the gate.

Wild Arms and Final Fantasy 4 easy item dupe bugs, FF6 power leveling on the river without playing, FF8 card conversions and junction system, 12's gambits letting you power level without playing. Most Bethesda products.

I believe this is the correct answer.
