The impact of J. R. R. Tolkien's Lord of the Rings on an expanding war game industry was to bring a new direction and a new way of creative thinking toward the way gamers played war. Wizards would replace infantry, towers and dungeons would replace bunkers and bases, and opposing armies would consist of monsters and hell spawn. With the addition of enchanted items, magic and weaponry, Dungeons and Dragons was born, and with its birth, a whole new genre of gaming appeared in playing cards, on boards, on personal computers, and in game consoles.

However, even as RPGs diversified and evolved with the rise of the personal computer, the Internet, and the gaming console, the marks left from the Lord of the Rings can be observed. In the use or mithril armors, in the concept of fighting monsters, or when exploring a world that invariably involves mountain passes, caves, and wizard towers, it is likely the RPG has borrowed the concepts directly or indirectly from this J.R.R. Tolkien's trilogy.
