America's Army: Proving Grounds 

A free first person shooter created by the government funded by our taxes. Its sole purpose is to brainwash the current generation of kids into joining the US army and thinking that war is actually pretty close to Call of Duty

Averagekid - "Oh look a free game on the internet! It's called.... AAPG....America's Army: Proving Grounds??? Guess I gotta prove myself haha!

(2 months later)

Averagekid - "I spent so much time playing that my grades have plummeted, and I am now a failure. Time to join the army!"

Tony Hawk's Proving Ground 

The worst Tony Hawk game I have ever played. Trying to make a button mashing game challenging by making you have to combo EVERYTHING is just stupid. Even the distance challenges seem glitchy, where you have to get about 10 feet past the Sick marker for it to actually give you a sick rating. Most of the challenges require tons of trial and error and way more patience than it's worth. Sometimes it's even hard to find a challenge, because they're scattered all over the place, and there's still the annoying gaps to find which have very vague names that could mean anything and you either have to gap everything or just look online for the gap locations

Tony Hawk's Proving Ground sucks.
