Umm...Your notes were completely different and Yugioh didn't become big until the 21st century in America. Now if you really want to think about the 1990's who remembers MS Dos operating system and the old style point and click adventure games like Space Quest, and of course the games like Wolfenstien and Doom.
As for Nexon....the games you listed are also new I mean REALLY new, Combat arms and Dungeon fighter have only been around for a few years.
My Account is 547080, yes just numbers, I made it in around 2001 for Maple Story.
As for the poll, Time, I'd rather live life and see the world evolve then to live life to the fullest in a single life time, this being said, this decision depends only on how much time and money.
