Jan 8	comment	Retrieving components from game objects (entities) 'Systems maintain a list of the entities they're interested in.' Sometimes you just need it spelled out to you :) Thanks, I was missing this point! Would it be reasonable, however, for an EntityManager (or Engine) to maintain a list of these, and the systems themselves just have a reference to the list. That way they wouldn't have to have worry about new entity registration/removal to their list, and could delegate that task to the more generic EntityManager class. That class would then manage entities for all registered systems.
Jan 8	comment	Retrieving components from game objects (entities) Thanks for the link to Richard Lords post. Along with your answer, that has has seriously helped my understanding. I now know that I was missing an EntityManager (or Engine) class and was trying to do everything (wrong) within the game loop between the systems and entities directly.
Jan 4	comment	Retrieving components from game objects (entities) I've had a play around with the Artemis Framework, but this is still performing type checking. It effectively uses a repository pattern for each type of component, checks what type a component is and adds it to the correct repository for retrieval later.

Dec 27	comment	XNA 4.0 - strange blueish alpha with Spritebatch over Skybox It could be that you are clearing the scene on the first line of your code with a blue tint ? `SceneFactory.Graphics.GraphicsDevice.Clear(Color.CornflowerBlue);` Try changing the colour to white and see if that helps as a first quick step.

Dec 14	comment	XNA Moddable Game - Architecture Design and Reflection Yes, I'm using abstract classes to have some very basic implementation of, say, the `IInputSystem`. I was just wondering whether mixing interfaces together with abstract classes was the done thing. I don't want to have to get all the modders of certain systems to have to write the same basic code. I can't mark a comment as an answer, but if you'll like to put one in, I'll mark it.

Dec 14	comment	XNA Moddable Game - Architecture Design and Reflection Cool, would it be seen as ok that abstract classes can make up part of these base projects too (`MyModel`), rather than just having them consist of interfaces ?
