Has anyone looked at Fighter Squadron - WW1 http://www.fsww1.com/

Nowhere near the polish of WOFF but as a complete overhaul of a WW2 sim to convert it to WW1 it's not bad.

The stable of aircraft is very good.Also included are early tanks which are driveable and have missions supplied for them. You can cycle the gunner positions same as an aircraft!

There is no campaign and the AI is a little suspect. But it's a free download, and a great deal of effort has gone into it.

Even includes WW1 naval aviation!

Worth a look for a bit of fun.

I flew it for a while, what, 15, 16 years ago? It was okay at the time for a moment but it didn't grab me. One thing that I thought strange was I always seemed to be in a cone-shaped valley and the more I climbed the deeper the valley got and I always seemed low. I never got a sense of proper altitude.

I didn't even realize it was still around, so I don't mean to dissuade anyone from checking it out. It's been so long I'd even take a look at it for grins but I gave away my SDOE disc years ago.

I was working with FS-WWI as an aircraft developer. If I say anything about FS-WWI, it's that despite the dated graphics, it had many really nice features that were ahead of it's time. One was a complete but rather fussy SDK for adding content like buildings and aircraft. Also a physics engine that used embedded properties and code in the 3D files, that you could adjust with the proprietory Open Plane Studio developed for SDoE.
