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++?

Yeah, except I don't think most game engines use the STL - they all end up writing custom classes.  Last time I looked at the Doom 3 / Quake 4 SDKs they didn't have any STL references.
