Küçük bir metin tabanlı macera oyunu yazmayı düşünüyorum, ancak dünyayı teknik açıdan nasıl tasarlamam gerektiğinden özellikle emin değilim.
İlk düşüncem bunu XML'de yapmak, aşağıdaki gibi bir şey tasarlamak. Büyük XML yığını için özür dilerim, ama ne yaptığımı tam olarak açıklamanın önemli olduğunu hissettim.

<description>A small kitchen that looks like it hasn't been used in a while. It has a table in the middle, and there are some cupboards. There is a door to the north, which leads to the garden.</description>

<description>The garden is wild and full of prickly bushes. To the north there is a path, which leads into the trees. To the south there is a house.</description>

<name>Woods</name>
<description>The woods are quite dark, with little light bleeding in from the garden. It is eerily quiet.</description>

<!--
a door isn't necessarily a door.
each door has a type, i.e. "There is a <type> leading to..."
from and to are references the rooms that this door joins.

Açıkçası bundan daha fazlası olmalı. İnsanlarla ve düşmanlarla etkileşim, ölüm ve tamamlanma gerekli eklemelerdir. XML ile çalışmak oldukça zor olduğundan, muhtemelen bir tür dünya editörü oluşturacağım.
Bu yöntemin herhangi bir çöküşü olup olmadığını ve bunu yapmanın "daha iyi" veya daha standart bir yolu olup olmadığını bilmek istiyorum.
