I wonder how big that download is.
I don't even want to calculate that, but luckily all the games can be downloaded individually. Some of those games are pretty big though.
And someone over at GOG calculated that if you write a review for every single game, then you will actually get more blue coins than that pack costs.
While there is a lot of junk in the pack, there are also a fare amount of games that are considered to be good in it, namely:
Alien Shooter gold pack (3 games)
Cryostasis
Death to spies+expansion
Faces of War
Fantasy Wars
King's bounty series (3 games)
Men of War series (3 games)
NecroVision+expansion
Pathologic (deserves bold so that people notice that gem)
Reign: Conflict of Nations
Real Warfare series (2 games)
Space rangers series (2 games)
Star Wolves series (3 games)
Theater of War series (2 games, 3 expansions)
UFO series (3 games)
XIII century series (2 games)
And a grand total of 86 games/expansions (mainly games), for less than half the price of a single new game (alien shooter gold pack counts as 1 game).
