From the campaign:
What does 4x mean!?
It means eXpand, eXplore, eXploit and eXterminate and usually only shows up in games that cost $50+ and take 2hrs+ to play. Well not anymore! Tiny Epic Kingdoms has all the strategy of a traditional 4x game without the cost or the long playing time. Tiny Epic Kingdoms is only $16 and takes only 30-60 minutes to play.
In TEK, you are a tiny kingdom with big ambitions. You want to expand your population throughout the realms, learn powerful magic, build grand towers, and have your neighbors quiver in fear at the mention of your name. The conflict? All of the other kingdoms want the same thing and there's not enough room for everyone to succeed...
