Share your own game rules you have made up that are not the way the game was originally meant to be played.
One that I remember is in “Monster Jam” for the Nintendo Wii, there is no free roam but you can play a “destruction mode” that has a time limit but works good enough. There is a map where you can go up on a roof and the goal is to push the other ones down being the last one standing when the time hits 0. That’s it. It was inspired by an flash game with the title “one must fall” I believe.
We played this a lot. Its funny how you only need a “interesting” physics engine for a game to be fun.
We used to play a “serial killer” game in Red Dead Redemption. The goal is to kidnap a woman without getting seen by anyone. Its actually a lot harder than you would think because female NPCs are RARELY unescorted in the game. It opens up an element of planning and stealth that you (or at least I) don’t usually use in that game.
