The initial plan was for Save Haven to have 3 parts; if things went well with them and fans wanted more chapters, then yeah, it would be a possibility for Jim to write more.
Are you serious? Paying 2$ or more per game a year/every 2-3 years (because that’s what is it, a game; even if it’s called Part 2, it’s not just “a plus,” it’s pretty much a second app, the second volume of the series) is not “too expensive”. It’s like asking Cataphrak if the third book of Infinity is going to be 2$ max, since Guns of Infinity was about 5$, or else the series are going to be “plain unaffordable.”
1$ for 200k (200.000) words of game? Buddy, for 1$ you usually get games that have 50.000-80.000 words (“short” games), and even those may cost 2$. Do you go for a coffe and ask them to lower the price to 1$, or buy a book and claim that it should cost 3$, or else it’s going to be “too expensive”?
And not to be (personally) rude to you, but what you’re asking for is disrespectful as hell. You’re misprizing and underappreciating Jim’s efforts (because these things take time, a lot of time he could use to be with his family, spend on his hobbies, or whatever he wants) and the sacrifices he makes by considering that the game “isn’t worth more than 2$.” Because not only it takes a lot of time to make them, Jim also has an editor, and surprise: they cost a lot of money. The money charged for Part 2 will be mostly to cover for the editor’s fees (and even if Jim ends up making more than enough, it’s fine, because guess what: he deserves it). The same way you want it to be 1$, others would demand that it should be free, and that’s what is plain unaffordable.
If it wasn’t called Part 2, and it was a different app (like with Guns of Infinity, The Lost Heir and many others), would you be asking for the same? For the next volumes to be cheaper, since the first one was priced 3/4$? Because the Infinity saga is going to be about 5 books, and I’m pretty sure that people understand that they have their own worth because they are their own games, even if they are part of a series.
If you still don’t understand it, it’s like buying the first Harry Potter book for 15$ (I don’t remember how much they cost): you know the following 6 volumes are going to cost about 15$ or more, too, right? You won’t expect any library to sell them for 5$, or give them away for nothing, even if you have the very first one.
The total would be high because there would be a lot of parts; anyone who has all of the Harry Potter books is bound to spend quite a bit, regardless of if they are regular editions or exclusive (because guess what; they are 7, a lot). Yet no one is complaining, because people bought them over the years (a decade or so), so the spending seems minimal, it’s insignificant. Or going to the movies; watching a whole saga of 3 is more expensive than a standalone movie, it’s just simple logic: + games/movies/books = + money.
A CoG’s price (about 3-5$) is cheap enough that anyone with a few bucks to spare can allow themselves buying one a month (or more); heck, there’s people out there buying starbucks’ coffe (5$ or so) weekly or daily, and they don’t go broke. And if you can’t spare that a year/every 2, 3 years for a game, then maybe you should watch your expenses carefully and buy ZE:SH rather than another video game/book/movie/etc. as a form of entertainment (you can’t have everything in life.)
