If I had unlimited cash, I'd buy em all. However... with Vikings/HP somewhat on the horizon, I'll have to vote for just Vladrek's Fortress right now. Gives me all I really want. 1 set of all the new knights, new vladrek, vicious new shadow knights and a great castle.
If I find I have some extra cash, then the prisoner wagon, for two extra shadow knights. Possibly the prison cave.
Then I have to deal with Vikings: Big Ship, Fortress
HP: Graveyard, Mermaid.
*Sighs* I need a better job hehe.
Dreams are only unrealized realities.
