Hi pavul and yes welcome! I believe we already met on Discord. Regardless, sorry I did not get to this last night, a car accident shut the electricity off right when I was going to start my reply until just now.
Allow me to address each of your questions directly.
Radialgm it will be replacing lateralGM or enigma?
Yes and no, it will be another complementary tool for ENIGMA. Emake is already pretty much complete, minus our new EGM format we are still designing, and can be used in place of or along with LateralGM. RadialGM will be the same scenario because we have no current plans to end complete support for any of them. However, my own development focus is going to be shifting more towards RadialGM.
is porting to mobile platforms in the work road?
Yes, if that was you I met on Discord last night, then you actually walked right into the middle of discussions about mobile. More on this later, but we're working on SDL and cleaning up our graphics systems to add OpenGL ES support. We're making considerable progress with that actually as fundies shared just the other day he has the SDL platform working in Firefox again using Emscripten.
is lateralGM or Enigma still maintained?
Both are still maintained but my development focus has shifted to ENIGMA as well as RadialGM. The only attention LateralGM is getting is where it's absolutely necessary to continue to bridge the gap with the new Protocol Buffers and such.
does this tool or team the goal of create serious or maybe commercial videogames? ( because i am )
Yes, and this is becoming ever-more increasingly one of our top goals actually. There are other supplemental goals as well though, just that I personally find it fun and I also like having my own hackable GM that I can just add my own stuff to.
should i use LateralGM along with Enigma to deploy games or wait until RadialGM is released? ( because currently im working in a new game yet in development state)
For now, please continue to use LateralGM as it is the most feature complete. I will certainly be making everyone aware of when the RadialGM beta becomes available. To save yourself the hassle when the beta does arrive, you should use the newer MSYS2 setup if you are on Windows, or just use the regular Linux setup. This will ensure you have most of the dependencies installed through a package manager and you won't have to configure as much.
