Wreckfest actually has two things that are weird in it that are almost second games The bonus ride-on mower racing mode And the bonus DLC at christmas called "Throw the Santa" where you launch santa out of a convertible into a giant christmas tree to see how high up you can get
On y8.com there is a game called Just Car. Basiclly it is a game with you and a.i doing random stuff on the map. You can fall out of the map. It is just weird.
my favorite youtube channel for top tens is watchmojo. here's a video called top ten weird video games.
Star Wars on the Famicom is pretty weird. It has something you'd never expect to see in your entire life. I wish I was making this up. This was the only video I could find showcasing this.
Some more weird games I know of: Cho Aniki. Don't Google this game, you may regret it, unless you're an absolute trooper. I discovered its strange existence when I watched PewDiePie play it, and I was like WTF throughout the entire video. Seriously, what planet did this "game" come from? Hong Kong 97. Don't even get me started. Happy Wheels can be weird at times. Trollface Quest games is very, very, VERY weird if you ask me. Then again, what do you expect from a series of games named after the trollface? The Impossible Quiz series. I don't even want to explain why.
I'd say dating simulators are weird. If I remember it correctly, I once saw a 'dating simulator' on a top 10 of weird games that involved dating birds. And with 'birds', I don't mean that you're dating a feathered anime girl version of, say, a toucan, but actual birds. I was like 'what the heck?'.
Driver San Francisco One of my favorite games, but...you are playing as a man who is in coma having weird dreams.
