Speedrunning. Can you beat any games in 1 sitting? You can be a speedrunner, give it a shot! Some easy ones are:

1 - Oblivion. The Any% category is extremely easy. You learn 1 exploit to pass through walls, then you walk straight to a door that takes you to the end of the game. You can beat the whole game in ~20 minutes with absolutely no practice, and ~4 minutes after practice.

2 - Portal. Specifically the “Inbounds” and “Glitchless” categories. It’s a very short game with interesting mechanics, and tons of room for creativity even without glitches. But the insane array of glitches at your disposal make the game’s skill ceiling crazy high. The glitches range from extremely simple to insanely precise and esoteric, but all of them are fun!

3 - Quake. The original Quake. It can be tough to find a comfortable route for all of the levels, but it’s a relatively short game and all the levels are not very long. Getting good at running Quake is a matter of improving your movement rather than an exercise of memorizing as many glitches as you can, so it’s one of the simpler games to get into, yet it still has a crazy high skill ceiling.

4 - Super Mario 64. Another game that’s a blast to run without any glitches, but even more fun when you do learn to exploit them. Similar to Quake, getting good at running this game mainly involves improving your movement rather than learning to exploit a bunch of glitches. Simple game with a high skill ceiling.
