Travian is a building strategy game set in the period of classic antiquity. Gamers take the part of being chief of a village of either Romans, Gauls or Germans. Each nation has its own advantages and disadvantages. Right after registration, gamers start building their village up from only one main building and few fields for producing ressources. As soon as gamers have erected the first few basic buildings, interaction with other gamers becomes possible. There are alliances to forge, a market place for trading, and wars to be waged with the help of trained units.
Exactly! These scientific stieuds are normally carried so badly that the results can say whatever the researcher wants: They select a group of ppl based on a trait and see if they have another trait of interest to correlate with, then make the announcement . This is statistical bullshit, if you don't control other variables? of the study (on this case, I can think of parent behaviour, brain activity of the lineage, socio-economical status, etc) you can't say there is a relation.
