With all the Argo Online hype right now, I decided to check it out. I managed to record a couple introduction videos. I thought that the artwork was quite a bit interesting so I recorded them. It should give you a general information between the two races. At the end of each race video, you will find what each race looks like in-game and short skim through tour of the playable classes available in Argo Online. Maybe these videos will give you an idea of which race you would like to play when you get your hands on Argo Online.
