Ritual Entertainment were briefly known as
Hipnotic Entertainment. They cut their teeth making the excellent
Scourge of Armagon. At that time they were working from one of the employees homes, and got into
trouble with the law for running a business in a
residential area. There is a rumour from this time that regular visits from
John Romero (wearing - I kid you not - a
cape) had convinced neighbours that they was a
drugs ring operating from inside the house.
They went on to produce the immense pile of suckage that was SiN and the (apparently not that bad) F.A.K.K.2 tie-in game. Their next project is probably another shooter. Developers with a similar background and area of expertise include Id Software (natch), Raven Software, Rogue, Ion Storm and Xatrix Entertainment (now Grey Matter).
