The hellgate should be unironically moved from Jerusalem to France. The French IRL were the birthplace of a large chunk of modern degeneracy so it wouldn't be that much out of character for them. Secondly this would streamline logistics for everyone involved as no unnecesary bordergore and immediate encirclements would be needed.

The Pyrenees and Alps should be the frontlines due to their inherent deffensiveness as mountain ranges. The British should be patrolling the coast of Europe to make sure no hell forces manage to escape the continent. The east is dependant on how many factions you want to have there. I think having Warsaw and Konigsberg be under siege would be fine enough to have both a Polish and German faction in the game.

>I know people complain about the Islamic faction a lot
Just put Al-Andalus as the Islamic faction and have Iberia be split in the middle between Christians and Muslims. Have the reconquista be effectively put on hold for a while to fight the forces of hell. Occassional conflicts between the two sides happen but they are usually short lived.

Now because you have two factions in a prime position for colonisation you can divide the new world between the two and any additional colonisers and even natives.

Spain kills off the Aztecs and gives the Tlaxcallans the right to run the area while at the same time telling them to provide resources for the war effort in the old world, and they get to fight a hell outpost created by corrupted conquistadors gets set up arround Lake Guatavita (The inspiration for El Dorado), made up of demon worshiping natives and traitorous colonists. Flamethrowers and obsidian bayonets in jungle warfare.

Demonic pirates of the Caribean doing naval battles with the Military order of Malta to protect the resource shippments from the new world.
