The following games are installing correctly, but the shortcuts/icons are missing: abuse chromium clanbomber gav glaxium icebreaker mahjongg3d monsterz powermanga stratagus Most probably there are more with missing icons, but these are the ones I have installed on my system...
Mass-list bugs aren't very helpful. If you really care about an icon, etc. for a game, work up a patch for the ebuild and file a separate bug per game.
Also, we tend to not create our own icons, so if upstream doesn't provide one, we likely won't either. The best place for this stuff is upstream. While we know that isn't always possible, we try to stick with what they provide.
