Quest 64/Quest 64 vs. Ireland

Quest 64 is set in the land of Celtland. The map in the intro is very similar to Ireland, one of the six Celtic nations, alongside Scotland, Wales, the Isle of Man, the English county of Cornwall, and the French province of Brittany. Note that Celts pronounce "Celt", "Celtic" etc. as if they were written "Kelt", "Keltic" etc.

Lots of names in the video game are Irish or Scottish:
 * Brian, the hero's name, is a very common first name in Ireland.
 * Shannon, the name of a recurring character, is an Irish female name as well as the name of the longest river in Ireland.
 * Dondoran, the name of the first castle in the video game, means "Mole Castle" in Irish (Irish spelling: Dún Dobhráin, same pronounciation; dún/don=castle, dobhráin/doran=mole); the people of Dondoran actually dig the ground to get clay. Bundoran (Bun Dobhráin) is a real town in Ireland.
 * Connor, the name of a forest, is another typical Irish name: think of the Irish singer Sinéad O'Connor.
 * Glencoe, the name of another forest, is a real location in Scotland (Scottish spelling: Gleann Comhan, same pronounciation); "glen" and "gleann" mean "valley" in Irish and Scottish, respectively.
 * The Isle of Skye is a real location off the coast of Scotland.
 * etc.
