Losing game interest with age?

I've taken to game creation in my older age in an attempt to not only rekindle my interest in the quality gaming I've grown up with but to perhaps benefit from contributing an accurate portrayal of that to others. Compared to commercial success I would make a strong venture, based on personal experience, that this is massively more rewarding on a small scale than a large one. If you can create the game and have fun both being creator and producer, that's the dream if you ask me, and it's a vibe that people will deeply appreciate if you can deliver.
