good hint, Mirefox
after having played many standard and basic games it felt so natural for me to only think on the Basic game for a tourney that i forgot to mention it
i have edited the announcement post.
regarding the maps the players on each table can vote for or agree on a map all players own.
if any players only owns the maps which come along with the game, then one of those will be played. no one should be obliged to buy a map to play in the tourney.
