Well the main issue is purely one of cost. How much is the MOM name worth. $50k? $100k? $150k? $250k? $500k? $1M?
Game development is a strategy game too.
The big unknown variable is sales and revenue.
Let me give you an example. In The Political Machine, the developer's royalty is about $2.50 per box. On a AAA game like MOM, that royalty might go up to $8 per unit.
Now imagine the game development budget of say $1 Million.
Let's say, for simplicity's sake that we worked with MegaPublisher and our per unit royalty was $7 per unit. We would have to sell 150,000 units just to break even. And that's with no license cost to use the name.
Let's say your license fee on Game X (not talking MOM just generically now) is $140,000 (for easy math). You would have to sell 20,000 more copies JUST to break even on the name.
But it's really not that simple eithe because most licensing deals involve mostly up front payments. So the $140,000 example I just gave would come before the game's in the stores. That's enough money to pay for a developer and 2 artists.
GalCiv was developed by 2 developers and 3 artists. The Political Machine was done with 3 developers and 2 artists.
Imagine what we could do on a fantasy game if we had nearly twice the art resources?
Or more to the point, which would generate more sales? The licensed name or the additional features/content that would come with having a larger development staff?
Hence, we put up this poll on GalCiv.com and in about a month and a half, in which every MOM site has linked to it, we have about 1000 people who answered to it, 500 of them said they'd pre-order it. So to the person who thinks it's a no brainer that the MOM name would generate 20k in additional sales, don't be so sure.
So ultimately, it boils down to trying to figure out the demand for a fantasy turn based strategy game in 2006 on the PC. Game development studios don't usually have a long life (Simtex, for instance, is long gone). These kinds of decisions have to be made carefully.
