How about a compromise?   average of the last N games?


if totalplayed is < N, use your algorithm

                   (totalplayed * oldrating) + currentscore
    newrating = ----------------------------------------------
                              totalplayed + 1


Once  totalplayed >= N, then it becomes a rolling average of the last 
N games played

                   ((N-1) * oldrating) + currentscore
    newrating = ----------------------------------------------
                              N
