Let's just get this out of the way. And for the love of God, if you're going to pitch your own original story, don't post walls of text. Sonic games were never novels. Keep it simple stupid.
The only thing I'm wondering is where is Metal Sonic? Is he just staying back until Robotnik calls for him? Other than that, yeah, this story is good. Simple while giving support.
He's just a final boss for Tails and a mere robot. He doesn't play a large role other than following orders and beating shit up. You know, like good robots.
Okay, but that raises the question of whom Tails fights in the stages. Does Tails follow Sonic and fight Robotnik until Metal Sonic intercepts him for the final showdown, or does he get his own new boss character?
I figured Sonic and Tails stuck together, then they split off. Sonic goes after Robotnik, and Tails takes on Metal Sonic. Does that apply to Knuckles as well or is Nack the main bad guy he goes after?
As much as I like the general idea of this story im not too keen on the fake Master Emerald thing, might be a bit confusing. Maybe Nack could simply distract Knuckles away from the emerald chamber by stealing the other 7 emeralds in a scene similar to the start of Sonic 3? Then with Knuckles gone we see a quick scene showing robotnik coming out of hiding within the chamber laughing. Act 1 for Knuckles all looks fine with the island still floating in the background as you chase Nack but then at the end you see it crash into the sea. End of Act 2 has the fortress rising from the sea and a shot of robotnik in the emerald chamber having converted it into his cockpit for the island fortress. This way we keep the same basic story but avoid the hassle of the Master Emerald ever being removed, fake or otherwise. Plus with Nack stealing the regular emeralds we have an excuse for Knuckles to chase him and a reason for you to have to collect them again.
Anyway, I'd say that both the Chaos Emeralds and the Super Emeralds should exist. Sonic 4 is after Sonic 3 & Knuckles, so Hyper Sonic and Hyper Knuckles should exist, as well as Super Tails.
Will you stop strutting around like this? You're not a project leader anymore—stop acting like one, and stop being so condescending towards everybody. I'm getting seriously sick of it.
True, if that was the fake Master Emerald to begin with, how come Angel Island dropped in the first place? Unless Nack HAS the real M.E. but used a fake one to lure Knuckles away from the island becauuuussee... Robotnik wanted to attach his base on it?How come the island floats again then?! GOD, I'm thinking about it WAY too hard!
1. Robotnik wants the Chaos Emeralds. 2. Sonic, Tails and Knuckles prevents Robotnik from getting the Emeralds by going through each zone and destroying his army of Badniks. 3. Robotnik gets pissed and orders Nack to get rid of Sonic/Tails or Knuckles (Whoever you are playing as) so then that's when the Mini boss battle occurs. 4. ??? 5. Profit. Seriously, That's as complex as you need it.
Hmm...has anybody considered killing Robotnik off at the end this time? As in, maybe he accidently robotisises himself and breaks apart before the explosion. There is no Sonic game yet tha boasts closure ...unless of course you plan to make a sequel to this...
Eggman get's Nack to to trick Knuckles with a fake ME. While, Knuckles is chasing Nack, Eggman steals the real one, therefore the island falls. He attaches his base to it, and then puts the emerald back, and the island floats again.
Its a simple enough story when written down, I was just thinking about how to go about showing that ingame without too many scenes where you have to cut from one location to the next to show whats going on. The suggestion I made of Nack stealing the regular emeralds is reason enough for Knuckles to chase him but also avoids the hassle of having a scene where we have to explain that the Master Emerald was fake.
