KryzonSince he's using Adobe Flash it is most definitely vector art, designing the graphics using lines and curves the same way that you would do with other software like CorelDRAW, Xara, Illustrator, Inkscape etc.
Magic Particles looks like a decent program. You should also look at After Effects, it's the standard when working with motion graphics.
If you plan to work in a game studio it'd be essential to learn the particle tools in game engines like Unreal, Unity etc. -- you can look for hints of what software to learn in job postings looking for "game FX artists", and by asking employed FX artists what programs they use in the studio.
Thank you, Kruzon! I saw Adobe After Effect. This program does not have own system of particles, but it has several plugins and Magic Particles has plugin for After Effect too.

I don’t know, I will be work in game studio or no. Unity is the game engines for casual games and it has very simple system of particles. Perhaps, a plugin for Unity will be made in the program Magic particles someday. If I were developer the program, I would create this plugin. Especially, there are many games on site of the program.
As for UDK, it was created for huge games, and many companies do not make large projects.
