DIfference ww2 and ww1 game engine

[Kuniworth]

Can anyone tell me where I can find or prehaps the complete differences between the ww1 and ww2 game engine? Everything from units etc...

One of the biggest, if not the biggest difference is now a unit in contact with 4 enemy units(surrounded) will lose supply as it is considered out of supply(siege condition). I'm wondering if that holds true if the unit is an HQ?

When it first came out, the differences were massive, and I think the list can be found in the New Features thread.

The most important of course relates to trenches. In WWII games, units can entrenchment values at the start of their turn.

But in WWI games, they gain entrenchment values when they entrench, or move into a trench, and these rise at the end of their turn.

If not entrenched, units benefit from what is called Ground Cover, gaining it at the end of the turn, and this equates pretty much to entrenchment in WWII (i.e. it's beneficial, but not as good as being in a trench).

Plus the benefits of being in a trench rise with every level in trench warfare.

Enemy trenches cannot be seen through, so it is impossible to see what is behind the trenches without either breaching the enemy line, or using Recon Bombers.

Recon Bombers are much less effective in WWI in the ground attack role, and without research are only useful at spotting, though with a bit of research into Ground Attack Aircraft they can become fairly useful at that.

In WWI the unit slot for rockets has the characteristics of Airships, whose evasion for air interception increases with every level researched, as does their range and strategic attack.

In WWI, Seaplane Carriers use the slot normally used by aircraft carriers. The Seaplane Carriers really aren't very useful except for reconnaissance, and don't have the same options as do aircraft carriers, e.g. they don't have any fighters so cannot intercept or escort.

In WWI, the slot used by anti-tank units in WWII is occupied by cavalry, who are good at scouting but not at all good at defending.

This probably isn't comprehensive but it should give an idea of some of the major differences.

It's a resource that if it has 4 enemy units adjacent to it will start to serve less well as a source of supply, decreasing in effect by 1 point per turn, though capitals and fortresses aren't affected by this rule.
