I'll just be interested to see how all of us who've benefited from KS this year do in the future.
I desperately want all of my adventure game projects to be successful, if not wildly. QFI is actually the one I'm least concerned about, because I've played it, and it's great. Mind you, it's a slice, and we don't really have much of a window into an overall plot-arc from Demo 1.0, but it's obvious that you'll be able to execute on the game. The physical rewards are another issue. I hope you'll keep us informed about the process involved in putting together the boxed versions and the awesome tchotchkies that go inside it. I do worry a bit about how that whole "reward fulfilment" aspect of KS campaigns. I still haven't given up hope on the idea of a QFG/Sierra style guidebook, with hints masked and revealed via red-cellophane decoder :-)
After QFI, it's
Detective Grimoire, since they're really far along (shooting to ship this month), because I've already played the demo, and because they have publisher support via Armor Games. Then, it would be
Reincarnation: The Root of All Evil, because I've played about six of his little free Reincarnation games on Newgrounds, have seen some of his behind-the-scenes Youtube videos about doing keyframe animations, and have already received all of my physical rewards (yesterday), so I know he can write/design fun little adventure games.
After them would be
Lilly Looking Through, for similar reasons as QFI; I've played a nice demo, and all they have to do to deliver is finish (I'm not getting any physical rewards from them). Also, I've read statements from other Kickstarter backers on other projects that they were able to meet the Hoogendyk's at either GenCon or Dragon*Con, play an extended demo, and that they're really really nice. So, they're sincere and the game is already progressing well. Also, they've given themselves plenty of time (est. release next May).
Then, it would be Broken Sword, since it's a more ambitious project, hence greater chance of failure, but Revolution Software is an established studio with plenty of experience, a dozen titles under their collective belts, and soon, a goodly chunk of change. Right after them, I'd say it would be Tex Murphy, because of precisely the same reasons. They've got a studio ready to go and shipped titles, albeit casual games, and the two (Aaron & Chris) are veteran game designers, as well as having a goodly chunk of change ($600K aught to help).
After that is probably Eric Shofe's
The Curse of Shadow House because we've got no forum access to keep up to date, and he hasn't issued any updates in a month, other than some banter on the project comment thread (in which, admittedly, he can be quite verbose; a good thing for Kickstarter updates). He's trying to ship by Halloween, which seems aggressive to me. His project has a smaller scope, though, which will help, and he's hinted at putting game quality above release date, which is good.
It's murky after that... I think Jane Jensen is probably next in my line of worry, since the studio is brand new, and the development work is contracted out, but they have another title (Mystery Game X) with publisher monies, so the studio will probably be in reasonable shape. Plenty can go wrong there, but they should have enough cash to get the job done, and she and her husband are seasoned game development/publishing veterans.
Then, my worry-meter is squarely aimed at SpaceVenture and Jack Houston. Both are trying to build a studio and game from scratch; both have had budgeting problems (the Two Guys are going to face fulfilment issues due to the redonkulous quantity of swag they've promised, and Stacy at Warbird Games got straight-up screwed by a troll backer, to the tune of ten thousand smackers, a fifth of his budget). Both haven't published a game in a long time, and both need a lot of luck to hit it out of the park. I'll do whatever I can to help out, for sure. I'm really keen on those two projects (SpaceVenture being extra special to me).
