How hard is it to code a game in C++?

I'm just wanting a rough estimation here, but I, like most of the 4chan community, have ideas for games, or movies, or what have you.

So I'm learning C++, and I'm doing pretty good with everything I've learned so far.  I'm only taking a beginning course in my college, but I'm still doing good in it.

So, if I wanted to create a platform game, or a fighting game, or even a tile game (Pokemon Clone), how hard is it?

If I already had all the graphics, all the story written out, and all the gameplay mechanics worked out, how long, and how hard would it be to create a game from scratch, using just C++?

Now thats just mean. What I would say, is that if you have the patience to learn / become proficient with DX or OpenGL or both... and database programming and tuning, artificial intelligence, server lag / rubberbanding smoothing issues and other general network comms issues, collision detection, Game theory / mechanics, economics, 3d modeling in a program like 3dsmax, shader languages like hlsl or cg, creation of textures / bumpmaps, sound programming/engineering/recording/postprocessing... you might be almost ready to start making all of the mistakes that will make you efficient enough to make a game that might be played by people other than youself and your friends. Or maybe it might not..
