If you're a loyal CastleVille player, your incentive to try Zynga's newest Facebook game FarmVille 2 has just increased, as the games have come together in a cross-promotion, offering CastleVille players free items in their Kingdoms for trying and eventually leveling up in FarmVille 2.

There are three stages to this cross-promotion, with different items being awarded each time you reach a certain milestone on your new farm. For instance, for reaching Level 3 in FarmVille 2, you'll receive three Dye Kits back in CastleVille. For reaching Level 10 in FarmVille 2, you'll receive three Steel Bars and for reaching Level 20 in FarmVille 2, your final reward is a bundle of Rifting Scepters.

Obviously, all of these prizes are items you could already have in your Kingdom anyway, but being given them outright saves you from being required to craft them yourself (and waste those crafting materials in the process). Good luck!
