From https://bugs.kde.org/show_bug.cgi?id=450481:
Some more consistency in the naming and order of the *other* activities would also be nice, e.g.,

1. always show the ‘against Tux‘ before the corresponding ‘with a friend’ activity (it’s this way for most of them, but not for the ‘Align four’ activities),
2. be consistent with the use of parenthesis (used for most activities) or not (oware activity),
3. be consistent with ‘against Tux’ or ‘against the computer’,
4. be consistent with ‘with a friend’ or ‘with your friend’ or ‘against your friend’).
