I see. Sometimes ideas grow and become better as time goes on. The better game ideas I've had have been put on hold but kept coming back in my mind, but then better formulated and with more engaging interaction. So I wouldn't say that it's a bad thing to put it on hold.
That was my thinking exactly. I still like the idea but I realized the project was too ambitious and I wouldn't be able to do it justice at my current skill level. That's why I'm working on some smaller projects right now to get more experience.
