LOL.. if only! I have been playing nethack for years and rarely get past the castle in the mid levels. I just can't sit down and play it for hours anymore. Its more of a diversion for me now, but its one of my "must haves."

I have had variations on nethack (Rogue, Angstrom, etc) on almost every portable device out there from WM and Palm PDAs to my n810. Still nothing beats the real thing.
