Jumping back to the original topic, I'd personally be most likely to cough up actual cash money for games that make use of the less common controls- Steering Wheels, Trackballs, Spinners, Analog Joysticks, Flight Yokes, Lightguns, etc. The reason being, there are just two many joystick and button games already available for free, legalities aside.
But I'd seriously consider paying for a good game I could play with a flight yoke, or a spinner. Or even crazy stuff like a spinner in one hand, and a joystick in the other (try
Aztarac!). Or whatever, the point is, I would pay money for something that I don't already have too many of. Joystick games, I've got too many of.
This isn't as hard to implement as one might think, either. 360 degree wheel, spinner, and trackball games all just need mouse control enabled. Analog joystick, 49-way, and Flight Yoke games all just need to make use of the analog controls on a PC gamepad or joystick. Games using these controls can also have digital inputs enabled, so that they're still saleable to joystick & button gamers, they just need to make use of the better controllers when available.
Now, I
would consider paying for a joystick & button game, if somebody comes up with something truly original. But lately, it seems like shareware makers mostly just do the same game styles over and over again. I just can't see paying $10-$20 for a game where my airplane/spaceship shoots up wave after wave of enemies while the background terrain scrolls under me, you know? Ditto for a game where shapes/colors drop from the sky and I have to try to stack/match them up. There's just too many of those out there already, why should I pay for more? Come up with something I haven't seen before, and you've got my attention.
I don't think there's enough of us to warrant a developers full attention for such a low price point.
There don't have to be enough of
us. It would be insane to create games from whole cloth just for emulation cab owners, for sure. But all developers need to do is take us into account when designing the games they release for all the other PC gamers, in order to add us to their potential customer base. All the developers
need to do is make sure their game's controls *can* be set to MAME defaults, and that all menus, title screens, etc. can be dealt with using the basic controls found on an emulation cab, and allow a 640x480 (or lower) video mode. They
can do more, (like a mode that uses credits, bypasses the menus, etc., and making use of analog and/or mouse input would be a big plus) but that's all it takes to add our community to the list of potential customers. As to the price point, it's up to them whether they wish to sell their product at that price, and I doubt that decision will be made on the basis of whether the games are made cab-compatible.
