Ok, I would like to make a simple 2d game in OpenGL. I have followed a few OpenGL 2 tutorials and think I could get my head around it. Is it worth learning opengl 3 or 4 simply for a 2d game?

if your just making 2d games probable not, you should check out zengl it might save you some time
You may want OpenGL 2 for compatibility with some older hardware, but if you are going to use raw OpenGL, if you stick with OpenGL 3 (Core functionality), it will be much less confusing and you will learn modern OpenGL a lot faster. My suggestion is to learn OpenGL 3 (ignore anything that is lower than this) and stick with it. As a bonus, you will find transition into OpenGL ES (iOS, Android) easier, should you decide later to pursue it.Originally Posted by 3Shrike3
Was it that some of OpenGL 2 and earlier commands don't even work on OpenGL ES?
Yes, that's right. Fixed-function pipeline don't work in OpenGL ES 2 along with some other deprecated functionality. This is why if you stick to core OpenGL 3, you get relatively clean API, which should be mostly exchangeable with OpenGL ES 2.
OpenGL ES 1.1 still has some legacy functions, but it is a deprecated API.
How do I load the dglopengl.pas file into my game as there is no .lpk?
you can make your own .lpk and add it to the list
Since it's not including any components or such there is no need for a package. Just add it to your uses clausel and put it in a directory where Lazarus can find (either where your game's sources are located or any of Lazarus' search paths).
Ok, so I've decided to learn opengl 3+. Noob question time: So I have to install dglOpenGL and what should I use for windowing if I want my game to be cross-platorm? Because glut is old I think.

I don't think we have any multi platform solutions at this time sdl2 would be a good choice if we had working header files. I'm using xlib at the moment. there is enough here to get you started if you speak a little C++
