Altough I feel some sentiment in your response and it feel pretty honnest, I would like a more factual response instead.
From the date you decide to do Jins, how many-man hours (you and collegue have put thru). I'll put some factor to take into account previous experiences, etc...
This is just to give me an overall idea of the current value of the business and decide my bid toward the asset.
It's hard to give a more factual response.
First of all, I can say only about myself.
Second, it's hard to assess the time spent on the project. For example, 2 years ago I was working on a MMOG project as a server programmer. Part of that project is used in Jiniri, but I can't say how big/small it is, there is no a way to measure it. Another example, a year ago I provided a back-end for a project that wasn't released because of funding issues. Part of it is also used in Jiniri. All these parts are algorithms that solve specific issues, but 0 lines of the old code will be used in Jiniri. From formal point of view I ought to say that exactly 0 (zero) hours was spent on the project.
You decide to create the Jinns project two years ago? For example, if this was all start 2 years ago, an upper bound woul be like 70 hours/weeks for you, if you dedicated 100% of your time on this. Are you working more than that
The idea is not to count every part that was made there and there before (if this is the case). Only count from the moment you said: I'm doing the Jinns project.
The estimation can be very crude. I understand very well that previous experience should multiply by many factor the man-hours that I am looking for. Anyway, if you can't give me any estimate, it Ok. I won't make a scene of it... lol
