Final Fantasy 9 - Memoria
This place is just...........wow. Copped this game for Christmas in 2000 and it was the first FF title I played and by the time I got to this point in the game it really felt like the finale. Everything that composed the creation of this level really changed the way I viewed video games from that point on due to everything that happened up to that point in the game, especially to Zidane and his crew. From the first area of Memoria to the last you are given that mysterious amazement feeling since each level changes entirely with their own atmospheres, sceneries (both eerie and beautiful), dream-like aspects, and histories. And each level presents many ethereal, otherworldly things including the creation of the universe, the heavens, the earth, the moons, the stars, the planets, the suns, and the galaxies. And the music was glorious.
