Pokemon Showdown is ridiculous. At first, I thought it was good, I was certain that it was fair game until I actually started battling people. I'll admit that I don't know a whole lot about battling but I know enough to know that the Pokemon my rivals chose where overpowered and a lot of the attacks they had wouldn't have been obtainable in the actual game. Not to mention, it really bothers me that they just happen to be the ones who go first.
Not only that but the whole deal with being able to switch your Pokemon in and out is unbelievably frustrating. I'm not saying that I would've won if that weren't an option, but I would at least have a fighting chance.
