I've been thinking about this for a while and I've formulated the steps I think should be taken for the next 3D Sonic game. I'm going to list my ideas, and I also want to hear what others think. So, here we go. This is what I think is most important: Presentation: I think it'd be cool to sort of combine the hub worlds of Unleashed and Colors and give players freedom to choose which level they'd like to tackle. Basically, in my mind there would be a relatively small 3D hub where you can chat with NPCs, unlock extras, and sort of just explore. From this 3D hub you access the main zones, which are presented as maps a la Sonic Colors. Each zone would have four acts (three main and one boss). Characters: the playable characters should go back to just Sonic, Tails, and Knuckles, with the option to switch between them at will in hubs. Sonic controls as Sonic does in the boost series. Tails is slightly slower than Sonic and can't homing attack, but can fly. Knuckles is the slowest, can't homing attack, and jumps lower, but can glide and climb. Customization: customization would be a huge aspect of my ideal game and would build off the skill shop from Generations and the Avatar system from Forces. You can choose which abilities you want the characters to have and what designs they'll use in-game, and unlock more using rings. You could choose between the boost and the spin dash, the slide and the roll, the stomp and the bounce, etc. The costumes would be based on past Sonic designs (Classic, Adventure, '06, Boom, etc.), and you can mix and match to play as your ideal character. Gameplay: For a new 3D game, I'd mostly stick to the Generations-style boost gameplay. However, I'd give players the options to toggle Sonic's physics between "Adventure" and "Modern" styles. It's sort of self-explanatory, but I'll explain anyways: in Adventure, the controls are more responsive and you have more control over Sonic, but he's slower and not as easy to control when he's going fast. In Modern, the controls are just like they were in Generations (a bit stiff, but easier to control when going fast and to maintain speed). The level design would accommodate both styles, and include alternate routes and paths only certain characters can access. Progression: Instead of a linear progression system like all the other Sonic games, it's more like Mario 64 or Banjo-Kazooie: progression is determined by the number of red star rings you collect, and you're free to choose which level you want to go to next. In my ideal Sonic game, red star rings would be more plentiful and easier to spot, so it's not like you would have to constantly backtrack. Art style: how about going back to Unleashed's? Story: I would continue from Sonic Adventure 2 without necessarily contradicting what's happened since then. The story wouldn't be needlessly complex, but it would have a big presence and would see Eggman trying to up the ante and outdo his previous plots, and Sonic, Tails, and Knuckles setting out to stop him. What do you guys think?
