I agree with what people said here. If you want a summary in text, it would be good to have someone who writes well about the game in native English. @Rayne would be one who has written many well-formulated answers here.
Am I proofreading, editing, or creating a small report of the player? I don't mind helping with it somewhere. I wouldn't be able to make reports with all the players, especially ones I am not entirely familiar with.
With Riut, seeing as how there's something nice of him already, here's what I know. Not a short summary, I'd have to trim it.
If I am not mistaken, he first came into the scene around 2007 with the nick MewTwo. Everyone knew this player was talented, because he was unusually fast and had great micro then for someone of a 2k rating.
Then when the name Riut was born, it became famous quite fast. Was playing Chris quite regularly if I am not mistaken, and that's when he started hovering around 2300-2400.
I think it was when Riut was in the [Viper] clan by Alma Negra (someone can correct me on this if I am wrong), is when he got serious attention after winning some [Viper] clan tourney, consisting of Hun wars on Arabia ahead of Daut, Chris, and whoever else was in that clan (which was like every top player). Believe that tourney is what sealed Riut's name in the aoc books.
There is of course Tyrant which Riut joined in 2013 I believe? Everyone knows about that stuff, and probably more than I do as I wasn't around much then.
As for his style and map, believe Riut should be known most for his incredibly strong Arabia play, though he could play any map. He is one of a dying breed if I can use those words, as he liked full feudal wars with many scouts and archers, which a lot didn't do -- very well to add. And Riut was exceptional at it, a true feudal warlord. Build order for it was steel solid, combined with his famous scout control (has anyone forgotten when Dreams made 7 spears vs 3 scs and said its because those 3 scouts were Riut scouts?) Not only that, but he was the fastest player alive. Entertaining play as well, as he often played with virtually no walls when he did this style of play.
How's that look? Too long? Not my best, but its just writing randomly while thinking about old times. Can tweak it.
I could maybe do this with a few others that I know of. I have known Nicov, slam, Yo, Fire, and Hera (sorry if I have forgotten someone!) for a long time so might be able to write something (I am sure they're willing to help me too if I pm here/voobly). I am not sure I could pull off Chris for instance, but I know some stuff outside of the oldschool tourneys.
