俠盜獵車手III
A game may combine aspects of multiple genres in such a way that it becomes hard to classify under existing genres. For example, because "Grand Theft Auto III" combined shooting, driving and roleplaying in an unusual way, it was hard to classify using existing terms. The term "Grand Theft Auto" clone has been used to describe games mechanically similar to "Grand Theft Auto III". Similarly, the term roguelike has been developed for games that share similarities with "Rogue".
