Torchlight 2 has hands-down the best animation I’ve ever seen associated with deleting a character.
OpenXCom is an open source clone of the original XCom: UFO Defense. The goal of the project is to run the original XCom on modern systems, with some bug fixes and modding/tweaking enhancements.
OpenXCom does require a copy of the original game in order to run, but that can be obtained fairly cheaply on Steam or GOG.
One Terraria fan used Arudino to create a Liquid Lifebar that fluctuates based on his Terraria character’s health. An LED-based version of something like this that would track game stats (preferably multiple such stats) would be awesome.
Vsauce has a nice look at the absurdities of video game inventories, noting a single GTA V character with all gun slots filled and with full ammo is essentially carrying about 800 pounds of gear:
I have to say, those GTA V characters are lightweights.
In Borderlands 2, a character can unlock a total of 43 weapon slots, and each of those slots could be filled with a rocket launcher. A real world equivalent weighs about 50 pounds, so a Borderlands 2 character with rocket launchers in every slot and full ammo is looking at carrying more than a ton of weaponry.
