There seems to me confusion in this sentence:

It is a "mini-guide for Dummies" was written with a tinge gamer, that is to say, made for an encyclopedia written by and for Ryzom "avatars". 

When you say 'tinge gamer,' i assume you are meaning, "written by a gamer with a little bit of a gamers point of view for the Encyclopedia for other players?"

Actually, a better way to say it is, " ...was written by a gamer with a little bit of a gamers point of view for other players, to be included in the encyclopedia." (or Wiki instead of 'Encyclopedia')
