Pheace: At least for me, I'm funding those games because I would love to see games/more games of those particular concepts
This.
As an aside, I backed the game. I knew when I backed it there might be issues. Hey, you pay your money you take your chances.
But (as others have said) I do think we're kinda seeing how the stereotypical attitude of publishers towards the unknown began:
Developer: Hey, we've got this idea for a new game. Take a look.
Publisher: Wow, I like it! It's original, it's a great story, yeah... How much to make it a reality?
Developer: Well, we've crunched some numbers, and we could do it for about $500k.
Publisher: Hmm... Okay, here's a million, just in case. Make it happen.
[eighteen months later]
Developer: Hey, you know that game we were making?
Publisher: Cyrillic Megabiff? Yeah, we can't WAIT to see it!
Developer: Well... we've hit a snag. We need another two million to finish it.
Publisher: Err...
[New pitch meeting]
Developer: Hey, we've got an idea for a new game. Take a look.
Publisher: Hmm... Well, we appreciate the ambition, but in our experience these things are far too expensive to make, and don't make enough back to cover the budget. If you take out features four, six and seven, we might be able to do business.
Developer: But... that would make it just like Paintball 2012!
Publisher: We know. Have you seen the sales figures for that thing? Look, do you want to make the game or not?
Developer: Well...
Publisher: Great! We'll set up a meeting to plan out the next year or so of deadlines. It would be advisable to not miss any.
Developer: But... but that's not our...
Publisher: Excellent. See you tomorrow!
Ah, well.
