first mover advantage.

you don't get that in scissors paper stone; and elsewhere, you don't get to learn from mistakes. Of course, maybe learning just means more information, interpreted and maybe a contributor to your downfall. So, that's tricky. But first movers don't always win. In fact, 2nd movers are often in excellent positions. Sure, the 1st mover will force you into limited options and your favourite move - a move that you're very good at and have a 90% chance of winning - may not be available. But then it's not available for good reason...it won't win this time. So by going 2nd, you avoid that. Great. Simple enough.
