What's true main story of "Yu-Gi-Oh" series before it was about TCG?


I have read the original of _Yu-Gi-Oh_ series ( The First Generation ). It
surprised me that the first chapter ( about 1 to 10 chapters of _Yu-Gi-Oh_ )
it's not about a _TCG_ (Trading Card Game) which people nowadays familiar
with. Formerly, the main story is about _Yugi_ and his penalty game, beating
some bad guy, compare it with _GX, 5D, Zexal, and Arc V_ which are already
about _TCG_ and Duel from the very first chapter.

Does _Yu-Gi-Oh_ actually not a series about _TCG_ from the first ? Why did
they change the concept of story all of sudden ? if it's not, Why the first
chapter of the story is not about TCG ?




In the initial stages of the manga, Yu-Gi-Oh was more or less supposed to be a
**horror manga**. Although the end result was a manga about games, it was
clear that some horror elements influenced certain aspects of the story. It
was later decided that "battle" be the primary theme. Since there were a lot
of "Fighting/Combat" based manga, it was in a way difficult to come up with
something original. Hence it was decided to create a fighting based manga
where the main character does not hit anybody.

Hence, the early chapters of Yu-Gi-Oh feature a variety of different games;
but from **chapter 60 (volume 7) onwards** , the most common game that
appeared as a plot device was the **Duel Monsters card game (formerly known as
Magic & Wizards)** through the Duelist Kingdom and Battle City tournament
arcs; receiving elevated plot relevance in the latter arc.

Other games still appear during the DDD and Memory World portions of the manga
and gaming, in general, is often referred to; the modern card game being a
recent fad in Japan imported from the United States within the original story.
