PLF C++ Library - plf::colony
Fast data structure for unordered-array-of-struct, especially for gamedev. However, the comparison with std::vector seems unfair, especially erasing, where you'd instead swap(v[i], v.back()) and then v.pop_back(). The main advantage of colony over other data structures I've seen is that iterators & pointers are never invalidated, so you can store pointers in other data you have instead of an ID/handle/index.

Game Engine Containers - handle_map
"This article explores the creation of a data container for game programming. This container is meant to take the place of C++ standard library containers such as std::map and std::unordered_map, with an alternative that stores data contiguously in memory."

Improved Heuristics for Optimal Pathfinding on Game Maps - AIIDE06-006.pdf
Dead-end heuristic uses a high level map representation to determine areas that will never be needed for a particular path search. Gateway heuristic uses a high level map representation to find waypoints. Both of these could be done with a hierarchical approach but this paper tries using the hierarchy to build the heuristic for the low level pathfinder.

The Role of Mechanics in Games : Dwarf Fortress
Dwarf Fortress's game mechanics are generic — the actions taken by each creature depends on properties of objects and not on objects. Instead of setting up a game mechanic where a fox eats a rabbit, the game sets up a mechanic where a fox eats anything smaller than itself that produces meat.
