The large european map for example has a 49 bonus for germany and similar numbers for other countries. Unless the income for the game is made high or commerce is available, it would make a player think its worthless to carry on if they lose even a small piece of their country.

I don't think they usually are.

I generally prefer if there are say region or province bonuses, but no huge megabonuses

Why not put a high income for territories instead of a fixed base income then? That way, every territory is worth armies, so losing 1 shouldnt hurt too much. (Assuming the bonuses are balanced with the income.)

you should have:
extra armies everyone X territories, I prefer 2
smallish bonuses of 3 to 8 territories
no mega bonuses
army cap and no commerce to stop people from sleeping all game and winning

I always keep megabonuses at a low value, no higher than t/6.

I agree, as in the maps are default like that for some of them.
