I've been playing this game for awhile now I personally think its the best curling game out there and with the right support i think it could be more popular and more competitive. In my opinion the rating should only change if you win or lose and be effected by the rating of the player not how many points you won or lost by. I really like the fact you naturally lose points if you don't play it makes it so you know everyone with a high rating is good. I wish there were more local/Smaller tournaments for maybe if you win you get a lot of points and a symbol on your name tag showing all your tournament wins or second third etc. I hope i can hear some other opinions to make the game better and i hope they are listened to 
Thank you for your time,
