Give me a challenge

[FinalAdvance]

I've completed a campaign as the central powers and a campaign as the allied nations. I managed to march all the way into Kreuznach before 1918 and now

Now I want to make the game fair on the AI once more. I need restrictions and handicaps to make this game difficult for me. I need a real challenge

 

[FinalAdvance]

Since no one else has given me a challenge, here are a few I made for myself.
Glorious Commonwealth: Win the game using only British, Australian, Indian, and Canadian units (all french, Belgian and American units must be kept away from frontline tiles)
Rule Britania: Win the game using only British forces (all french, Belgian, Australian, Indian, Canadian, and American units must be kept away from frontline tiles)
A vote against conscription: Win without using British or French Regular companies (elite are still permitted as are Belgian, Australian, Indian, Canadian, and American regular companies)
The Old ways are best: Win using only Infantry and artillery (no tanks, no planes, no observation balloons)
Where is everyone?: Deploy no more than 5 rifle companies of any veterancy and 2 artillery while defending. Deploy no tanks or aircraft on the defense (Emplacements that cannot move such as machineguns and mortars can be deployed freely without restraint)
Industrialization, That's how we'll win this!: Win the game without auto resolving, and without using Rifle armed troops. (machineguns, artillery, planes, tanks, Grenadiers, flamethrowers, and mortars are still permitted)

I'll add more as I think of them

Try limiting unit production to historical numbers or enforcing strict supply lines. Even the Top 10 International Law Firms in London couldn’t draft a loophole to save you from that challenge!
