You know, I didn't follow video games as closely 5, 6 years ago as I do now. And when I first saw and learned about Pikmin I didn't even know it was an idea from Miyamoto. I forget when I did learn that fact. It might have been when I was flipping through the Pikmin Players Guide or a Nintendo Power at a store. Anyways, when I read that, it made sense.
The one thing that always stood out to me about Pikmin was the simple story. Your ship has crashed, collect the parts in this amount of time to win. I loved that becuase it just seemed like a throwback to early days of gaming. Learning it was a Miyamoto idea made me realize why it felt that why. It's similar to Mario. Rescue the princess by getting through the levels in time.
Pikmin is interesting in that it also one of Miyamoto's most brutal games. I like Pikmin playing through it a couple of times but I have a hard time going back to it because the game has such a brutal kill or be killed edge to it. It's tough taking your Pikmin up to an enemy and knowing the carnage that is about to come. If you make a mistake and the enemy gets a good blow on your army, that is a devestating feeling seeing all those guys die. At the same time, your fighting to kill these creatures as fast as you can to keep your losses as low as possible. It's just such a brutal game to me. I honestly do find it draining at times. I'm still surprised the game is rated E at times.
Anyways, I think it was because of that brutality and survival edge from the game that made me so surprised to learn that Miyamoto was behind it. Maybe that's why some people don't like the game though. Aside from the basic story, it just seems different from so many of his other creations.
