Hello. I think that the current surrender system is extremely flawed...
As it is now, my Games looks like this:

As you can see, the first 7 haven't played in over 2 weeks (one in 2 months), and since I need them to accept the surrender I can't remove them from the Games -- meaning that 7 of my limited slots are unusable -- so as of now, for example, there's only one player online in my games and I can't start any new games...
So, my suggestion is to allow one-sided surrendering if the other player haven't made a move in X days (say, a week or so).
