The idea for the timeline is to have a levelled system to it, like a mini game.
So you roll the ball on a 2d side-scroller and when you roll on a panel it reveals e.g. Sonic and small info on why its iconic.
You reach the end of the generation and move to the next level which is the next gen and so on.
Whilst in the level you can choose to revert back or roll back to re-read information.
To have this as a solid idea to pursue i will have to do multiple checks on how this will be coded in action script 3. Amongst gathering the information and research from my survey which i am currently unable to attain as it requires money to unlock but i will sort that out soon. So a clear understanding on where i am going in this topic is now with me so i can really knuckle down into coding it.
