Just for clarification of the question and poll posed by
@Turin_Turambar, “bfme 2” is a reference to
The Lord of the Rings: The Battle for Middle-earth II, which
Wikipedia describes as
The Lord of the Rings: The Battle for Middle-earth II is a 2006 real-time strategy video game developed and published by Electronic Arts.
Game designers have pretty much free rein in adding
monsters to their play because monster encounters are one of the principal reasons people enjoy that genre of video games. In this case as well, since the reference is to
The Lord of the Rings only, the implication is that this is licensed through
Middle-earth Enterprises, formerly
Tolkien Enterprises, a division of Saul Zantz Company. The film and merchandise rights for
The Lord of the Rings and
The Hobbit were sold by Tolkien in 1969 to pay his taxes. (Taxes in the UK at that time were assessed by Inland Revenue: it sent you a bill, and you had to pay what it demanded.) These rights are therefore not under the control of the family. United
Artists originally purchased the rights for £100,000 and a 7.5% royalty interest in adaptations. Saul Zaentz Company obtained the rights from United Artists in 1976.
As an interesting aside the Amazon Tolkien series presumably
is under the control of the family, through its agency,
The Tolkien Estate. This brings to mind a quotation of Tolkien by his late biographer, Humphrey Carpenter, who cites Tolkien without further reference (p 226),
I cannot help feeling there is a lot to be said for “the grosser forms of literary success” as a sneering critic recently called it.
