Board Game Arena

I understand how to load them up but I'm curious about elements of game play that haven't been coded and will not work. For example, if I try to load a scenario with command cars or some other "advanced" type of troop or terrain, will it work? IOW, what elements haven't been coded and should be avoided? I'm trying to decide if it's worth my time to make a bunch of M44 files if they might not load.

I really wish you could just download the M44 file from the site like you can the PDFs but that's a different topic.

I think a list of what elements does not work online would be a very good "sticky post" to have.

If I understand correctly then the element that work with the Daysofwonder online version also works here. I usually make a version of my maps called "online" that has been verified to work on the computer. (My name is Nygaard if you search the Scenarios from the front).
