Hi Majid,
from what I have read for having succeeded with kickstarter you will have to give yourself a lot to do on a social level, it works if you have a community .. you will have to convince people, find them, do marketing for kickstarter too, I have never tried but I think it is the same as anything else that involves other people .. i'm skeptical here too, lol
however try and then let us know, good luck with the action RPG!
yes people appreciate more the best that today's technology can offer .. it means photorealistic 3D images, 2D makes you think something like 20 years ago for most people and it's a niche thing ..
personally in video games the thing I like most is the immersion in a 3D world and I think it is the same for most of the people, in fact I am thinking of developing something with VR ..
for music I create it myself, I have been making music for almost 20 years and the music / sound part is the easiest for me :)
