Nah, arcade racers. My whole family loves Hydro Thunder and wants a sit down.
Just FYI the Hydro Thunder arcade game isn't emulated.
The best you can do is the Dreamcast version on a Dreamcast emulator.
There is a PC version included with Midway Arcade Treasures 3/Deluxe, but the controls aren't analog so it sucks.
It will let you use a joystick or wheel, but the boat won't react any differently than it does to key presses.
I think it's worth $45, but it really depends on if anyone in your area wants it.
I had to give away a Virtua On and Daytona 2 seat on a craigslist curb alert because nobody was interested in them.
It wouldn't suprise me if the person that took them was only interested in the slider base for scrap metal.
You can get a more comfortable seat for around $100 off ebay.
