A *band or band is properly either Angband or one of its many variants. The star symbol in the name *band is used as a “wildcard” operator on many operating systems, and means that any bit of text can precede the term “band”. Hence, you find that many Angband variants apply this rule: Steamband, Zangband, Unangband, etc.. However, a larger classification could be made to include games of similar feel.
Moria, as the primary influence on Angband, can be considered a band. Technically, this category should be Moria-likes, since Angband is very similar to Moria; but the prevalence of the term “band” to refer to games of this genre leads to the *band term.
