Hi,
i own a license for Blitz Backdrop, so i'll make a comment about it.
Its more of an engine like Resident Evil or Nocturne, than a point + click engine.
You can code this yourself, but its more for resident evil style games at the moment.
I plan to use both Blitz Backdrop and Wintermute for two different types of games i'm doing.
One is similar to the longest journey (wintermute point + click), and the other is more
action based with zombies and shooting and action like resident evil.
The major benifit for me is you have the full source to be able to do whatever you want in
it. I'm a Blitz coder anyways,so i'm good with the language. But my advice is if your not
really a good programmer its not for you at this point.Wait until they release the next
version, which is supposed to be aimed more at artists.
I've been trying to get on the beta testing for the next version but i think they don't like
giving out a lot of info, pretty secretive about it lol,but Lee the main guy has given some
great support and always gets back within a few hours of e-mailing him.
I heard the new version is going to be a tool aimed more for artists where more scripting is
involved, a bit like FPSCreator from the guys who make Dark Basic, but for action adventure
games.They are also bringing the system to Dark Basic Pro, c#, c++ and Blitz Max.
So to summarise, its a good system if you know Blitz3D very well, Blitz is easy to learn
anyway, but if you can't program its no use to you, better off waiting till the next
version, don't know how long that will be though.
There are a lot of commercial systems and addons for Blitz3D that can be bought cheaply,
that intergrate with Blitz backdrop really well, i'm using some of them with my game.
Hope that helps!
