I was totally stoked when I encountered my first pyramid type ruin. It was so beautiful, climbing up the steps and fighting off zombies and skeletons while collecting loot. It seemed that enemies on other levels COULD attack you if you were near the edge, despite not being able to see them. At the peak, I noticed stairs down and took them, and continued down inside the pyramid fighting more and more powerful undead beings. It was very dramatic, especially if you visualized the dark and dingy interior, and whatnot. I ended up leaving after becoming thirsty, but I will never forget how awesome that pyramid was.
I can imagine (And hope!) that in the future, there will be legendary pyramids of massive size, loaded up like abandoned cities with all sorts of mazelikes paths and whatnot inside. At the core, of course, would be a dead king of ages past, decked out with gold and gems and splendor. If you survive getting down- or perhaps even the encounter with said dead king. Curses are curses, and all.
Just imagine the fun:
?Example Adventurer: Was born 1045, vanished 1063 exploring the Tomb of Fantabulo. Scholars are puzzled as to the sudden disseapearance of him and his companions.
?Fantabulo: Born 566, died 630. Was a powerful King, though not much is known about him. His tomb was lavishly filled with riches, but is also said to be guarded by spirits.
?Fantabulos Tomb: A Pyramid in the Desert of Painful Sun. It is the final resting place of King Fantabulo. It is said there is a curse upon it, though the song of riches lures many regardless. Very few who go there return.
