Moving you to our "Your Announcements" forum.
Do you have any experience that you feel qualifies you to offer advice to others?
You stated that "Python mostly belongs to the PS3 format". Apart from the fact that this doesn't really make sense -- perhaps you could clarify what you think you mean by "belongs to the PS3 format" -- it's also incorrect in that Python has no particular relation to PS3 at all. It's very viable on many other platforms, and is probably most commonly used on desktop computers.
You then go on to say "just like Ruby it is a tricky language to master". While mastering any language is a notable achievement, both Python and Ruby are generally considered to be very approachable to beginners, with other languages such as C++ are considered to be trickier.
In your section on Unity3d, you started by saying "we can't all be masters of programming languages", which is probably misleading given you can't actual create games in Unity3d without programming unless you purchase an additional third-party add-on to allow the use of a visual scripting system.
You mentioned Photoshop as "the only programme that is needed for designers". In Japan the term "designer" is typically applied to what western studios call "artists" or "graphic designers", and Photoshop is just one of several popular tools commonly used by artists. For a designer (in the typical western sense of the term) however, Photoshop may not necessarily be used much if at all, with Word Processors and mind-mapping software often being very important tools.
I don't want to be discouraging, but are you sure you're ready to be offering advice to others on these topics? If you wish to continue, you should probably do a little more research and proof-read before publishing further posts. Good luck!
