Bonus Content: Using Cages & Artworks
Cages are a massive part of Travian 4 but they are overrated. If you get a set of cages while still on your first village you should use them as it'll most likely mean that you can fight off any raiders who attack you, combined with your wall and your hero it'll make sure no raiding troops return. Don't bother buying any extra cages in an auction as I promise that later on you'll regret it later in the game when you realise the cages were overpriced and a couple of animals aren't going to cause a problem to even a medium sized force.
Artworks are very useful throughout the game and this means their prize on the auction block can go up massively, on the closed beta I saw one go for nearly 100K in silver, honestly the maximum they are worth is about 8K, don't pay anything above that. Don't use them as soon you get them, do some calculations, work out the point at which using the artwork will get you the most CP and let your hit the goal for your next village.
