Okay, but how many steps per second can an average CPU do? 10 MIPS is
pretty low-end these days. Even with 100 players, you're talking about
2% of the CPU.

PS: This a slightly simpler, faster and more correct atoi ;-)

short int = atoi(char *str) {
  while (isdigit(*str))            /* table lookup, one step */
    res = res*10 + (*str++) - '0'; /* three steps */
}
/* atoi("123") requires 3*4 + 1 = 13 steps */
