Tales of Ancient History
Moria, in the early 1980s, introduced the (unlicenced) use of Tolkien's Middle Earth setting into the Roguelike genre. From it came Angband (1990), greatly expanded and still going strong today. In gameplay terms, ZAngband (1994) took another major step forward by introducing a whole world to be explored outside the regular town + dungeon setting (while also moving away from Tolkien). On this basis, someone had the bright idea to take all these improvements back to Tolkien, creating Tales of Middle Earth – or TOME for short.
