@Nomad Soul,
If you are a programmer, you should know that complex apps are hard to debug to begin with. There is almost 64,000 lines of code with a complex engine. This is just not something like DBP or even C# where you develop a game from scratch using these languages. This is a language itself using DBPro to create a game using easy methods where a lot of the game making is behind the scenes so to say. It uses DBPro because it has commands that work with DirectX. There is nothing wrong with DBPro as a game making application. It has won kudos from many programming experts here in the states.
Then, you have issues with different computers. For some reason this can cause issues from one computer to the next. But not that many issues.
I hate to be pessimistic but it looks like FPSCR will not come to fruition anyway. I am not sure that they will every do a ground up or re-write using something other than DBP as the base language. Of course, I'm not inside Lee's mind but if it were me, I would forget about FPSC moving any further than v1.20 (apparently there is not enough interest in it) and concentrate on DBPro, the mobile game kit and the web engine. I am quite happy with v1.20. Especially for the whole purpose of it existing. For those young people and us oldsters who are just starting out in game development. For those who are young, they can develop fairly descent games right away until they learn to create a game in another language. Many have done that as there are many who have moved on from FPSC and we no longer see them. Then for us oldsters, we don't have the time to learn how to create a game from scratch using another language. Some of us aren't even familiar with programming. There are those who possibly would like to create a game for educational purposes. These could be teachers who could use the ease of FPSC. Sure, it would be nice to have FPSCR which includes ease of use, more quality and etc. I feel if you want to get into the AAA Indies level then you need to use another language. There are only 300 supporters for FPSCR. If there were 2000 supporters @ 25 sterling and 200 to 300 others at a larger amount, that would mean an awful lot to TGC. It's the small amount of those who are wanting to see this happen that is disappointing. If there are only that many, how can there be a guarantee that there would be that many supporters for a complete re-write?
This just my humble opinion.
