I remember seeing A* Pathfinding project (Normally $100) bundled with an FPS kit which essentially costed 125$ on the asset store somewhere, wonder how well it worked for them (Maybe you could ask them?).
So I think, you could sell them as Package deals :
Like Selling NGUI + WindWard/Starlink OR TNet + Windward/Starlink to give real world examples of those systems running in action.
$125-150 would be a decent price to ask for such bundles.
If you throw-in everything + Tutorials exploring the project (refer to Mecanim Animation Tutorial for a format of what I am trying to suggest), you could essentially sell these packages as a Noob-to-Pro learner package which will teach you most of the things you will need to make a game. Not only do you ensure that people will buy it with much less hesitation, but also you bring them into the Tasharen Ecosystem from the very beginning.
Say, you introduce the package in the form of chapters, (AI, Networking, UI, Pathfinding, GameLogic etc.) at a frictionless price point ranging from 15-25$, they are much likely to learn and buy more to build upon when they like it.
Your target should be to replace that Bootcamp project as the top learner project series.
It will be a fair amount of work, but with the new - larger than ever - wave of Fresh Unity developers coming in (after Unity 4 Free for Mobile announcement), it makes sense to make this bet. Remember, these are newbies who want to jump-in and get ready made code along with video tutorials to back them up. It would be a wise idea to try your hand at a new product : Especially for a company whose Cash-cow Flagship product which will now be competing with the Free GUI solution to be offered by Unity 4.2.
You could also strip off the assets and textures and merely sell the game logic along with a few scenes covering most use cases.
Unfortunately, if you are targeting people who are new and willing to learn - what would sell the kits is how beautiful the screenshots look. Your call on that. The assets would be just laying around on your machines anyway if you don't.
As for me, as a warmed up nerd getting a hang of C# and interested in Multiplayer, I would be personally interested in buying the projects just to be able to learn from it and would gladly pick them up for 75-80$ a pop without a thought and if they were priced at say $150, I would think a few times, but I guess I would eventually buy them.
Alternatively, you could sell the entire source code and assets for a big huge price tag of $300-500 depending upon the project and see how it works (another experiment). Even if it sells 1 unit every 2 months, does it amount to similar profits with reduced support costs? Wonder how many units The substance database or Mixamo plugin sells in a month. Not many I bet.
Just random thoughts.
