It could be VERY fun
You we need goals/targets to achieve.
The most valuable strategic asset of WW1 is recon. So it should probably be flying a recon missions and attempts to prevent them. We have some "dual-seaters" for recon so it can be quite doable and fun.
So some simulation of reconnaissance should be done the way it would actually be fun (not just fly to area 12,11,3) but actually detect some unknown stuff...
