"Frontier type game..", "Kick ass graphics engine..."
This is exactly what I've been dreaming of on the Amiga for many years now.
The gaming world is an overflowing plethora of first person shooters - some of them pretty good like Battlefield 1942, Call of Duty etc. What the (new) Amiga platform desperately needs is something like 2260 to make it stand out from the crowd. A Quake III clone simply isn't enough, no matter how pretty it might be.
I believe there's a market for a game which offers a universe to explore, open ended gameplay, eye candy and infinite possibilities to interact with the non-linear storylines, characters etc - a la Frontier but with a better graphics engine / gameplay / development / detail etc. If such a piece of software supported on line gaming where real players could interact then it would be a winner.
