I believe you mean interactive, meaning more buttons to push! And it depends on the series of F-18 your talking about too. I think maybe a Garmin 3000 sim cockpit would be a decent setup. Similiar to the Cirrus Vision Jet today.
But, that would be significant overkill for most games.
Keep the ideas coming....
Virpil has also sticks for Space sims. Noobifer(?) is a huge fan of their products.
speaking for the cockpit mean something like this.
The trailer from Tippis Shows working AI and physic girds i think
