Howdy there, i'm looking for a digital cheap game to occupy my time at my bro's house. Needs to be sort of cheap and usable without a mouse and able to run on a MacBook uncustomized, don't know the stats, only that i have 2 gigs of ram. Other places are welcome, and i'm open for suggestions, but i prefer games that has very low emphazis on a mouse. I am into RPGs.

Thanks in advance!
