  • Shockbolt’s (64x64) graphics are distributed under the following licence:

    The Shockbolt Angband 64x64/128x64 tileset is copyright (C) Raymond Gaustadnes 2012. It can be found in the file lib/tiles/shockbolt/64x64.png.

    Permission is granted to:

    • use the tileset with in-development and released versions of Angband

    • distribute and make copies of the tileset with in-development and released versions of Angband, as long as no fee is charged for it

    • incorporate tiles designed by the author for variants of Angband and use and distribute them with Angband under the terms above

    Permission is not granted to:

    • modify the tileset without the author’s permission.

    • incorporate tiles designed for ToME that do not appear in the Angband tileset.

    • use or distribute the tileset with other games or projects. If you want to use and distribute the tileset with other games or projects, you must obtain explicit permission from the author. Non-commercial games or projects may be granted permission to use them, and if so, use will be allowed as long as the game or project remains non-commercial. To use them in commercial games, a non-exclusive licence must be acquired from the author.

    Currently some of the tiles in the 64x64.png tilesheet were resized from tiles made by David Gervais for the 32x32 set.

  • The font files are all by Leon Marrick and/or Sheldon Simms III and/or Nick McConnell, all of whom have agreed to their Angband work being released under the GPL.

It is considered good practice to retain this statement for derivatives, rather than (e.g.) redistributing Adam Bolt’s tiles under the GPL, or choosing to make a variant which is only under one of the Angband or GPL licences. This allows easier sharing of changes between variants.
