No worries, I am always open to discussion.
As a matter of fact, I love the idea of transporting goods and units, because having railroads that will lead you accross vast continent in no time is unrealistic.
The lack of oxen carts in my game is due to the fact that I have not managed yet to build enoguh buildings that produce goods (damn Byzantines) so one oxen cart (there is another one now)
was sufficent to transport that little goods that I had. I expect this to change in the future.
As for the archers and city instalation artilery, I try to use the strongest artilery I can get (trebuchet currently) and it's advantage is that I can use it in defence until I decide to take initiative, and when that happens I don't need defence instalation anymore. I recon that I save some money using same artilery for both purposes.
I beleive I put some Paladin with those crusaders, as I have lost couple of them earlier and now I am aware that they need some cover.
I got an impression that AI is constantly getting better outcome in mellee so I built lots of catapults and try to avoid any contact before enemy is destroyed or redlined. Otherwise, I would lose too many units and my costs would go through the roof.
Bottom line, if I don't use some of units does not mean they are useless, they just don't fit in my playing style, and there are probably players who can find good use of them, and even kick my ass with those units.
Oh, yes, fortifications. Chinese took two Byzantine cities that were in the middle of my territory and the fortifications had temporary role to prevent Chinese from making nasty surprises while I was engaged against Russians.
So if anyone is interested in trying this mode in PBEM, I am willing to participate.
