Did these events really occurred 200 years before The Game Of Thrones????

Sole purpose of inventing and using High Valyrian language is to make the viewers believe that the events in the series belonged to an era 200 years before The Game Of Thrones.

But the team has seriously spoiled the realistic approach by allowing characters to wear some highly fashionable costumes, even weapons (not shown much), cutlery ietc. And the sets look more or the same as in The Games Of Thrones.

I hope they will improve this later or it is too late??

Two episodes and I am still waiting for the some interesting story or script.
