I knew about that.
Suggestions would be great.
It's no longer fun to make tic-tac-toe anymore. I'ld like to search for something i can do as a project but something that's not too easy or too hard because if it's easy i won't be motivated to start it and if it's too hard, i won't be willing to do it if it involves things i don't know about because i like to finish my projects but don't like jumping back and forth through a tutorial or learning process.
Okay, well that's good. You are making progress and want to expand your horizons, excellent.
So do you want suggestions for a project? Or are you asking if you would be better to switch to a different language to move forward?
If you knew about that, why don't you just take one of the suggested games from that list (Pong, for example) and just make it? You won't learn anything by just sitting there and dreaming about grandiose things you're going to do, because without any skill to do it those things remain just that - a distant dream.
People here have suggested you few C++ libraries that WILL help you at making the game as you won't have to begin by reinventing the wheel and can focus on problem solving with "lego blocks" that are offered to you. Once you learn basic concepts and get researching and problem solving skill by building those simple games, you can move on onto larger things.
