PC releases that do not match the $NAME-$GROUP scheme.
These may not be wrong but some are from known groups using the aforementioned scheme e.g. ReVOLVeR, TiNYiSO, SKIDROW, …
The rest may not belong to any group maybe they could use NOGROUP? e.g. Advanced.Battlegrounds.Future.Combat-NOGROUP
There are already some NOGROUP releases.
