There are pictorial checkmate and functional checkmate obviously. But if it is just a pictorial check do you have to move out of it? Usually no apparently, because the rules will have changed by your required turn. Both kinds of checkmate lose, but unlike pictorial check, the player does have to move out of functional check on his immediate next turn.
What would be interesting and challenging is to play Many Rules with different armies, or even with traditional polypieces: http://www.chessvariants.org/diffmove.dir/polypiece.html.
That could make for important subvariants of Many Rules with Different Polypiece Armies preferably on enabling 8x10.
