1) I believe that to start a topic in editing, you need to have worked on the project. At least to a level where screenshots can be made.
2) We already have Sonic and Shadow as characters, both with equal stats. We really don't need some sort of Dragon Ball Z "merger" of the two.
3) To be a "mod", a project must actually change how the game is played to a significant degree. For example, Mystic Realm is a mod. Shadow addon character is not. SRB2 Riders is a mod. Additional individual levels are not.
4) Storyline or no, it can't be implemented in SRB2 to make a character better. SRB2 focuses entirely on gameplay over story. Point best made when you look at SRB2's story and realize that it's really nonexistant.
5) You should make projects on your own. Not ask for help, unless you have a specific need for it. For example, Shuffle would need someone to sprite things for him if he decided to write up some wierd SRB2 modification. Someone does not need help if they start out making a character. They need to have the guts to do it correctly, and finish it.
I think I covered all the errors and problems this topic faces. Please let me know if I missed one or more, so I may rectify it/them.
