BTGBullseye sorry about choosing the wrong word, I meant game developer or game designer.
Rarity, I appreciate for your answer. This helps a lot. I am thinking it would probably be fun to be in a position that you design games but really I don't rely on only playing part of it. As you said, designing and creating would be much fun for me than playing.
Thanks a lot for the softwares and other information. I will definitely test them and try to find out which skills I have more talent for. I was always thinking that to be a game designer, you have to know some programming that's why I thought to study CS would make more sense. However, as you said it could be possible to learn the required skills through internet.
I think it is great that you can find tutorials and tips which makes the learning part easier or at least reachable. I wasn't experiencing the same thing in my field. Again thanks a lot man. One more question are there any other forum sites that I can follow and improve my knowledge about game designing?
