Yeah, I really liked minecraft back in the day. For some reason I wanted to make a minecraft inspired shooter, though.
If I recall correctly this idea originated on a Gymnasium (think highschool) orchestra retreat that I (kind of secretly) brought my notebook to. I used every free minute to code those minecraft graphics. What a passionate musician I was!
Highly ambitious project, since I wanted to make it multiplayer and what not, but actually just wanted to focus on OpenGL development, which was super fun. I always liked the idea of working on something that may not go to waste (apart from the learned skills), only rarely a project got finished back in those days.
