I certainly wouldn't want to do one for less than that. $100k probably wouldn't even really be all that tempting once you figure in all the time, materials, testing, at least a couple whitewood iterations, sounds/music, voice actors, graphics, animations, etc.

$350k, and I might actually run some numbers to try to figure out how feasible it might be and if it's worth my time (so I wouldn't be working for pennies per day).

But also, I'm not interested at all in BMX. If I'm going to spend 2-3 years developing a game from the ground up, it has to be something I'm actually somewhat interested in. And 2-3 years is probably optimistic, at best.

3D printing, molds, and vacuforming would save on tooling. Otherwise, tooling could be $10-$30k for an injection mold, depending on how complicated.

A laser cutter isn't *too* expensive as industrial tools go, although there are cutters you can outsource to, which would probably be ideal for one-off stuff.

A lot of the concerns of mass production aren't going to surface, since you would probably be making less than 5 games. But, then you have the expense of one-off stuff and the difficulty in finding places to outsource to who are only interested in high volume. There are some benefits and drawbacks.

Yup, big difference between a production-grade game, a decent homebrew game, a rethemed game with some customization/alterations, something cobbled together from parts, and a game with just some new artwork slapped on it.

Prices will certainly be different in each category.
