Hey. Sorry if it's bad protocol to resurrect a slightly dated thread but I want to say something and I'm just going to anyway.
OP, I've asked myself that question for a long time. It comes down to if you love doing it, like doing it, and where you see yourself in relation to the given culture. You know, I've had my own site for almost four years, I pay my monthly fee to keep my domain, I then give away all of my music such as it is for free. Even in all that time, nobody knows me, I know I'm not particularly talented, and yet I still press on. Why? Because it makes me feel good. What else matters? Would it break your spirit if someone tells you that they listened to your tunes, and found them simple, boring, poor for x number of reasons, etc? If so, that's a good time to consider yourself and the reason you wanted to create music in the first place. It's just my opinion that if the central focus of making music is for praise and recognition, you are not in the best place. If on the other hand you genuinely love electronic and chip music, in particular making your own creation just because you can, then why not? If there's little consideration to gains and losses, it then comes down to self satisfaction. Take me, I don't care if nobody ever knows me, I make chiptune, and am proud to be an active part of that culture. I can look at my tunes at any point and just feel awesome that I did something, created something that I can see and hear that nobody else has.
I'm sorry for the rambling, but basically, if you derive any satisfaction from making your own music, that's all that should really matter. You said you don't much like your own tunes. Based on what metric really? How about using none, make your tune, enjoy the process, and leave it right there? Besides, if you listen to your own tunes and are not satisfied, this is part of the fun. Make it satisfactory enough that you don't mind jamming it in your own car. If you truly find you don't enjoy making your own music, then no, I suppose it makes no more sense than say crafting furniture out of wood but in the end find that you hate using tools or smelling sawdust. I would just urge you that if you love chip music and can in any way enjoy simply making it, don't fret so hard on perceptions of good or not good, just keep doing it. Creation of anything does wonders for the soul.
