So I feel like a roguelike is something I might be able to do, or at least attempt. I'm wondering if there are any good beginner resources? May a good open game thats easily modifiable that I can get some ideas of how to go about my own?

I'm choosing roguelike partly for a low graphical requirement and an ability to have layers of complexity of game interactions (which I think is simpler to do and for players to grasp in this format?).

Where would I begin?

The RogueBasin seems a good place to start.

Have you already had look at this?

Edit: Never mind, found the accompanying youtube tutorials, thanks!

Also, I came across these myself. They might help you if you decide not to use ncurses or simple ascii rendering :)
