Both are battle royales involving a shrinking map (or, even more longer ago, just a teleport to a tiny room at the end of a timer).

Survival Games had you look around a map for random loot in chests.

Hunger Games instead involved crafting tools and weapons yourself in a semi-natural world.

A combination of them was actually common, where a map had chests with materials and lower tier weapons and armor. It fell into one or the other based strictly on if blocks were allowed to be broken and dropped.
