Well if you can draw even sort of ok you can kind of combine a few things.
You could start your own little 'webcomic' of sorts and catalog your adventures in a game of your choice. You could do something more fantastical that doesn't follow a game tit for tat (sort of an origional story), or you could do an MSPA type thing of any of the above and have posters input what happens next.

Here's something that pretty much everyone knows about, but I'll post it anyway:

I'll also see if I can get a friends Pokemon pen and paper DnD game rules to post too.
