My wife has made some on several occasions.
We used 80% venison, 20% pork, but I've also done some with lean burger and *I think* we used cheese as a binder. It was good, but different. The cheese tended to crisp up on the outside, which you might not prefer, but we liked it.
We made medium-sized ones so that they wouldn't over-cook, but would still cook evenly. They worked really great on hoagie sandwiches, by themselves, and cooked into pasta.
I'd recommend you cook double what you plan to use, then save the rest in the freezer or fridge for future experiments.
Spicy meatballs are another great option, especially if used as appetizers by themselves.
