I've seen games progress from very basic, to full blown almost cinematic quality. It can be difficult to see how you can compete. I started with 8 bit computers and by the time we got to Playstation I had given up trying to make games. I didn't even dream of making 3D until I came across a little program called Dark Basic. Since then I have realised it is not as hard as it looks to work with 3D (at least when most of the work has been done for you). At the time when 3D came into vogue I just thought, well that's it for me, I am not capable of the maths involved. Dark Basic was a revelation and is THE reason I continued coding and trying to make games. Yes, it wasn't as fast as I wanted, but it gave me something to work with ; up until this point I thought my games making days were over, leave it to the professionals I thought. Thankfully I found DB and got back into games making.
The tools you use will always limit your output quality wise, can't be helped. We just have to use what we have to the best of our ability to get our game made. I know how much work goes into making a game, it's one of the reasons I went for Reloaded (GG) in the first place. Making the process way less of a bind to get started. The problem is of course finishing one.
My advice is not to look at what has been made or is being made, that just leads to one conclusion - Stop now, I can't compete. If you enjoy it, carry on. I know I have enjoyed the creative process, even if I haven't actually made a game I can sell. I do it for the love of making something, I have long since stopped looking at what is around by other people. Don't make the mistake of giving up because of the quality you see, you won't get that quality without time and effort. We have to learn this stuff. There's no short cuts beyond buying GG to start with
I'll also add, most decent titles these days take a little more than a solo programmer. The days a programmer can make a game from scratch by themselves died at the end of the 8 bit era. Since then an actual artist has been pretty much needed. It's pretty difficult (and rare) to have all the skills needed to make a game solo these days. Back when I first got into computers it was the norm, now, any game made by one person is regarded as amazing (as long as it is any good of course).
If you enjoy it carry on. It's all about what you get from it. Unless of course you can make a viable seller, then it's a big bonus!
