Now for my story.
The Adventures of Spider-man, and that's what the game is, literally the Adventures of Spider-Man.
Personally, I would give a more Saint's Row/GTA approach. Now by that I don't mean webbing up civilians randomly or going into stores or anything. Instead, I mean for a game in which you can play as Peter and SM. As PP, you would do random things of your choice unless you had to further the story. There could be a moment in the game where you have to get something from the store and there's a robbery or something. There would be interactive features, (
GO HOME: Aunt May want's something done.
VISIT DAILY BUGLE: Missions like in US and SM2.
GO TO STORE: Robbery
GO TO SEWERS: To explore or for a Lizard mission. They're places you can go that activate some event. Throughout the story,it would be subplot mania. There is the Lizard story, the Venom saga, and eventually the Sinister Six, the Green Goblin Story, and other villains. These missions would have to be activated by going to places. At first, it would be the Daily Bugle. For example, JJ tells you that there are Lizards= Lizard saga. People being snatched up by sand= Sandman mission. I actually like how that was integrated into Spider-Man 3 The Video Game. Although in my game the stories would actually have an affect on the game, it would be Mission part 2 or part 3 because you would have to go to different places to further the mission, but no icons because that takes away from the imagination. You could chose multiple missions at the same time, but you have a timer on each mission. Now this sounds like an interminable game,
but the timer element adds some guilt to it. Between each mission location(You know, Return here, go there, etc.) you have free roam, but if you decide to slack off, the mission will run out with some bad cutscene with MISSION FAILED. If you fail all of them it's GAME OVER with an ending having Peter Parker quit. If you succeed in all missions, you have an awesome cutscene. If you did more than you didn't do Peter is happy but realizes he has a long way to go and that the city needs him. If you have more failed than completed, Peter pities himself and thinks about quitting. (CLIFFHANGER!) Every time you start the game on Free Roam, it would say MISSION TIMER STARTED. The only way to free roam forever is to never start a mission, which is boring. So, just like PP, you have to balance your responsibilities! A finale mission is the is the last mission you choose to do. When you finish each mission you progress the game until all are completed. Each mission, however is like it's own thing. For example: You finish the Venom saga, at the end Spidey says oh I don't know: I'll never change, With great power, comes great responsibility, and the mission ends with him swinging into the sunset or something. So it's like you end the game every time you finish a mission and at the finale mission of your choice, he says something cool or does a montage through the city, and it's over.(Unless a timer ran out) I really like this "choice" system. Every ending of every mission depends on you.
