I've had some success with game assets, and the trick is to pick a single marketing channel where your audience is likely to congregate, and post to that channel consistently. More than that spreads you too thin.
For me that was Twitter, for you that might be something else. Tiktok is king, so if you have the time to create and edit videos, it's worth going that route. I'll be using Reddit in a future project.
Just be aware that marketing has a disproportionate impact on your success. I'd go so far as to recommend a 50/50 split between marketing and product creation.
