I'm documenting and exploring interesting game mechanics from various titles. Here are some interactive demonstrations with short descriptions. I will expand the library as well as add more games that use those mechanics.
Can be seen in Resident Evil 4 or Dredge. This inventory system requires players to arrange items of different shapes within a limited grid space. Players must strategically rotate and position items to maximize space efficiency, creating a puzzle element in item management.
In Citizen Sleeper, the number of dice used in the game is reduced over time. Player can mitigate this by using special items or abilities. Each dice can be used to make progress towards the goal.
The game Crow Country takes the real world year and counts down to the year in game during opening titles.
Turnip trading in Animal Crossing and auctions in Moonlighter. In Animal Crossing real time is used while the game is running. Player needs to make decision if they want to buy or sell at current price or wait and risk losing the stock.
It's Sunday! You can buy turnips.
Price: 99 bells per turnip
In Hollow Knight: Silksong, Rosary Strings let you convert loose rosary beads into persistent inventory items. Strings don't get lost on death (unlike loose rosaries), and can be broken anytime to recover their value, however there is a rosary banking fee for this security.
