They were minor in terms of budget.

I doubt RaD or Sony will be put off making a sequel if the sales of this one justify the investment in a sequel. In fact if they get ~2 million in sales for a game that get a metascore in the 60s I think they would be rubbing their hands with glee at the thought of keeping what was great about this game and tweaking what was not great to make a game that would get a metascore of 75-80. That should get a sequel a good 4 million in sales, possibly more.

The only time a developer is disheartened is if the metascore is low and the sales are low. If film/TV/music/game makers actually took reviews to heart they would stop doing what they do and go work in McDonalds. They only really care about reviews to the extent that they affect sales/audience numbers. Do you think the people who brought us the abomination of 50 Shades of Grey care that critics have panned the movie to the extent that even the positive reviews are only givig faint praise? Hell know, they are laughing all the way to the bank because the movie has already made hundreds of million of dollars.

A lot of the sales comes from marketing as well. I think if they made a sequel it would not be marketed as well. Many Sony sequels had the ability to continue their streak of good sales if there was a good marketing push along with it. I hope that Sony is more realistic, and if they decide to make a sequel have as big as a marketing push as the first.

That is why I think they may be put off with making a sequel despite good sales. Super bowl ads are not cheap :D.

I think any time Sony has a PS4 1st party exclusive launching in February, sequel or otherwise, they will do a superbowl ad if they think the game will appeal to a superbowl audience. It is possible that Sony might think a sequel to a fairly successful game needs less marketing because the franchise is already known. But I think they will still market their games to some degree, and use TV events that are appealing to a similar demographic as part of the marketing campaign. I can see Sony advertising Singstar on late season episodes of Idol, for instance.

I wonder what they will do with a doc? Weren't they teasing something earlier? Maybe that will recoup some of the costs; although it will cost more to produce as well.
If those sale figures are true, we are getting a sequel for sure. I hope RAD learn from the development and make a killer sequel!

I think they have to sell upwards of 2m to get any sort of substantial profit and for Sony to consider hiring them again.
