Yet Another Emerald Spire Land Rush Question

[Babacilla]

If I purchase one of the "D" hexes, I spend 2 prestige points to acquire the land, then I get 2 prestige points back, so there is no net change in my prestige. The only possible advantage is that there are more hexes adjacent to the hexes I already own.
The "B" hexes make sense to me, since my total fame score increases, giving me access to more and better magic items. The net cost for a "B" hex is 1 prestige point, because I spend 2 and regain 1.

Do I understand this correctly?

You are reading the "D" correctly but look at the "G" hex as well. The more hexes you have (including "D"s) the better the benefit from hex "G."

There also may or may not be things you can get later in the dungeon that make those B hexes better.
