I was working on sketching out some ideas for a new project, and realized that I was having some difficulty getting things to fit into an MVC framework (In the case, CodeIgniter) In a way I liked. While I believed this can be overcome by working with the design some more and figuring out a better layout, It got me to thinking: could MVC not be the best answer here? and If not, when is using MVC a good idea for a project, and when is it not?
I feel like MVC could be used for any web app, but I'm wondering when is it not the best solution.
