Thanks for all the replies, people!
As a flight sim buff I've bought and played many flight sims in the Amiga during the early 90s.
F18 Interceptor was very playable and had a good 'feeling', I think it's very well remembered. Had also only 5 simple missions which should be not that hard to develop... The biggest challenge will be to model the terrain of the San Francisco Bay Area.
By the way, in 1997 through 1999 I've worked in an Amiga Space Sim project as graphic artist, it had the working title "Lambda Sector" and at one point we almost got a deal with a famous (at the time) Amiga games publisher. It was looking mightly impressive, a Wing Commander clone but with full 3D graphics and effects that looked like Playstation's Colony Wars or PC's Independence War Edge of Chaos titles. I got some alpha 060/AGA versions in my Amiga but a PPC/gfx card version was also programmed. The project died when the lead programmer departed, to work in Futuremark, makers of the 3D Mark benchmark software (and now a space-themed game called Shattered Horizon). Lambda's website is still online after 10 years:
