Ok, i have an RPG in my mind that i started long time ago, but now i want to think in the future and i need people to please answer my questions.
I want to (i will try to) do it the professional way, i want this game to be very special, very good and i will care for my game like if it was my child. I want to take care of every little detail of the game because i don't want to fail (i would never allow this to happen) i want to go slow but secure.

I have future plans of porting the game to other systems (i want to do it on PSP because of the graphic system, but maybe it will be on PS2 or PS3) but as far as i know GameStudio cant be compiled in those systems so i may have to write the game from the scratch for the other systems, is that correct?
Maybe is better to use another engine? My plan is to use gamestudio because is very easy for me and is the only way i can complete the game for now. But if i have to rewrite it for another system I may do it.

Another question, is it better if i use trutype fonts fot my game? Is it better if i use bitmap fonts? It is very important because if i want to port to a new system maybe i have to use some "kind" of font system. I have seen somwhere that truetype fonts have problems because you have to have it preinstalled (but maybe you can tell the installer to install it on every user). What is better for triple AAA games?

Another thing is the music, i will use MP3 music, is there something i need to know about mp3? Is it free to use the codec?

What about the shaders? The only thing i know about shaders is that they are special effects that "some cards" support. IF i plan to port the game to another system like PSP, will the shaders work? IF i use shaders in my game do i need to add an option for people that have old cards? (If i use shaders the game will look very bad in old systems)

Well i may have more questions but for now, i am happy if someone with a little of experience could help me.

Thank you community!
