You are absolutely wrong. It sounds like you are only hearing what you want to hear. They can and most likely will sue you.
The important thing is not the lawsuit itself, but the time and money you have to spend on it. It's not even important if they can win because it might take years for the case to finish and I would wager that you will run out of money faster than the publisher will!"
I think it depends. If the book is for example, a fantasy book (which is certainly what it sounds like), but the game is a football game (unlikely for that name), then I'd say there is pretty much no chance of Jason being sued, as the two things bear no resemblence to each other. However, if the game is a fantasy game, or a role playing game of pretty much any sort, then the likelyhood that Jason will be able to be sued (not "will be sued") increases. This is also if the author of Deathquest has actually registered his name.
That said, the likelyhood of a lawsuit also depends on things like, how well known a trademark is, and how much money the suer has. For example, if I set up a McDonalds Laudrette, then I'm not sure McDonalds would be too pleased. Although whether they'd recognise it as a threat that is worth taking on is another question.
