To the developers,
First I would like to say that you two have done a great job with the simulation so far! It's already quite solid and playable and I'm excited to see what it will become.
Secondly, as a long time simulation fan, programmer, and former flight simulator technician for Japan Airlines I have a question/request: Have you considered providing for those of us out here who are crazy enough to build physical simulators to tie in with the software? I would love to build my own submarine control room complete with periscope, TDC, sound/radio nook, engine room etc all with real physical controls, lights, bells etc. HMS Marulken as it already stands is perfect for that and all we would need is the ability map physical controls to all in-game controls (whether keyboard mappings or directx buttons or axes) and output hooks to trigger indicator lights, gagues, alarms, sound effects etc.
This has already been done with other games such as Artemis Spaceship Bridge Simulator
http://artemis.eochu.com/ via the use of DMX outputs allowing everything I have mentioned to be accomplished.
If this is something you would consider doing I can promise you some impressive photos and videos of my envisioned sub simulator in use when it's doable, not to mention my (and likely many others') undying gratitude!
Thanks again for undertaking this impressive project! I hope my suggestions are something you will consider.
Cheers!
Gwen
PS - I already backed the project on Kickstarter. Anyone else here who hasn't should get off their butts and do so right now =)
