I am also in the computer games industry and have been for about 10 years+. I was approached about 2 years ago by someone who stated he had approval from AAP and polo's big individual players to make a polo computer game using their names and images. Obviously this is a good start.
However the person had no knowledge of the cost of developing a game. Hugh has given it a good start, but nowadays the cost of doing something 'properly' run much higher. Basically you have to get a publisher to agree to fund the development using the demo as an example.
I had talks with a number of publishers then to get their feedback and the basic reply was the same everywhere: the appeal is too 'niche', meaning none of the publisher believed it would have mass-appeal and publishers these days are all into building IP. This product at best would be a 'hobby'-product, meaning if an individual with a big wallet would be prepared to fund it, you could find a studio to make it, but it would probably never (even in its finished form) find a worldwide publisher to take it on and therefore is unlikely to make a decent return (although it might break even providing you run it as a low budget development).
I found a studio in Australia with the knowledge and ability to build it for about 1.5 to 2 Mio USD (this would be a very limited budget considering high end games usually cost around 15-20 Mio USD to develop and only for a PC version which is the cheapest platform to develop on).
A game of such quality, would sell for about US$20 (compared to 50-60USD for high budget branded games, meaning US$10 wholesale, so you would need to sell about 200,000 copies to break even which is a big stretch for a niche game. I would say 50,000 copies is already a stretch...
Therefore someone with a big wallet who is more interested in having his name on the first ever polo game would be your best bet.
Then again, I am a simple salesman (albeit in PC games), not an expert in developing games, and I would love to find my homework done 2 years ago to be proven wrong!
