for me that depends on the game, and how the other sections are going. If there are still other games going, I may keep going, and also if I am playing a much better player, sometimes I like to play a few more moves out to see how they close a game out. In chess I used to resign, but I played on in one game and managed to force a draw.

there is no right answer, I don't mind either way if I am playing someone and beating them. It is upto them if they want to play a game out, or resign.

It is you choice and don't let anyone tell you otherwise.
