The tome game is available for debian now source code at http://www.t-o-m-e.net tome stands for troubles of middle earth. I've found that game far more challenging than nethack about equal with adom ancient domains of mystery. Nethack is more understandable than tome since characters can have multiple descriptions depending on game map context. The most interesting I've found because multiple quests are available are adom omega tome and least of the three would be nethack and rogue.
