I think that the variety what make this battle pack great.
If you were to compare the Star Wars battle pack to castle you would need to compare it to the Dwarves Mine Defender. Both about the same price, both have small vehicle and good fig count. The problem is that for castle, unlike Star Wars is that the dwarf gets very repetitive and it comes with the lesser of the two styles of helms the dwarf line has.
The new Dwarf battle pack is better value to me than the troll one because I can get trolls easier than the dwarves.
For the Dwarves I can spend 10 and get 1 dwarf, I can spend 60 and get 4 dwarves, or I can spend 70 and get 1. Really no mid priced stuff like there is for the trolls, the crownies, or the skeletons.
The trolls by comparison have $3.5 get 1, $10 get 2, $20 get 1+ large one, Tower Raid, $30 and get 3 trolls, $40 get 3, $60 get 2+ large, $70 get 6+1 large, and $100 get 4+ 2 large.
Granted most of these come with figs from other factions but the dwarves are by far the hardest to get if you want more than 10.
The Dwarf Battle pack is a great value to me because it beats every other way that I can get them now. Even if there was an impulse set with a dwarf you would give up variety for parts. And with the dwarves I need variety at this time.
sorry if this rambles.....
