I wrote that post about a year ago and what's interesting is that back then I didn't have any ideas but as I got into it, followed other people's tutorials, learned new things and started making a few little games the ideas started to flow and now I have a massive list of game I ideas I want to work on! I guess the creativity just flows when you're actually knee deep in the trenches so to speak!
It certainly looks like you've produced a lot so far, which is pretty incredible! So many people don't really ever get started. I think you're certainly a lot more creative that you give yourself credit for!
