We've already discussed many aspects you mentioned. Replayability and expansibility is our big concern. The mod and my Common library are already open source.
From the perspective of someone who writes code for GTA for over 2,5 years I can tell you that the very first version of the mod might not have 20 different cases and a case editor but it still will be probably one of the most work consuming and complicated mod ever created for FR. I'm very thankful for those who already help testing the code, send donations, wish us good coding in forum posts. Your support is very important in the development process.
Thanks!
