im thinking that there should be a medal for people who have participated for 100% of their turns. of course, this has a limit, as it wouldnt be fair if those new recruits play one game and dont miss a turn. the reason for this is that these people spend a lot of time devoted to this, and it would be a fun little thing to show off, saying that youve never missed a turn.
suggested requirements: minimum of 100 completed games, and 100% completed turns.
bronze is 100 completed games with 100%
silver is 300 completed games with 100%
gold is 600 completed games with 100%
im not sure how often other players miss their turn, so maybe the requirements for gold might be too hard, or all 3 might be too easy. in that case, just adjust to fit.
