We should create an FAQ section on the website.
>> Which API will this project run off of? DX11/10/9?
DX9 is the core, DX11 could be an option.
>> Will this game have proper joystick support? (Throttle/hat controls recognized)
Yes, the engime supports unlimited mapping of axes and buttons for sticks.
>> Will this project have any adjustable filtering options IE AA/AF?
Of course it will; everyone should be able to play it even on modest computers.
>> Will there be any multiplayer?
>> Will there be any 5.1/7.1 audio like Descent 3 had with Dolby effects?
Since the engine supports multichannel surround audio, yes.
>> Will there be any absolute campaign tributes like D1 in the future? (Replay the whole original game in an upgraded engine)
I don't think we have the time to create more than the game we are working on now, but who knows, FANS might come up with such a thing?
>> Finally, will there be any possible legality issue that may interfere with the launch of this game? I'm sure we all know what the Mechwarrior name faced.
The game is not called Descent. There have been talks to make it an official Descent game, but they have been going very slowly, so we'll see.
