10 Incredibly Useful Mechanics Video Games Never Bothered To Explain
1. You Can Shoot Targets For EXP Without Entering Competitions - Kingdom Come: Deliverance 2

Kingdom Come: Deliverance II shares the same leveling mechanics with its predecessor.
It's basically the Elder Scrolls system in which you level up individual skills instead of your character as a whole, and while it makes for a more immersive and rewarding scaling experience, it does have one downside in that it makes leveling combat skills rather slow.
To improve your fighting skills, you have to get into a lot of fights (duh), which either means waiting a long time for a tournament to enter or getting into a lot of dangerous fights with actual enemies while you're still very squishy and slashable.
Except you can actually cheat the system a little.
It turns out that the targets used in the archery tournament secretly provide the player with ranged combat experience, even if you currently aren't in a tournament.
If you want to level up your archery fast, all you have to do is grab some arrows and then fire away at the targets to be instantly rewarded with EXP.
The process is a lot more efficient and safer than practicing on live targets, so you best remember it.
It might just save you from becoming a live target yourself.
