I like limited sparring (no kicks or no punches, for instance) and 1 to many opponents is also a great alternative to 1 to 1, if self defence in mind.
We have "senerio" sparring where we are given a situation that we have to fight our way out of. This can range from having a broken arm (one arm sparring) to being knocked flat on our butts by a sucker punch (one person standing, the other on their backs) it is really fun.
