Banished feels a lot like Age Of Empires, but there's no combat. The goal in Banished is just to survive. You've got to manage your resources really well , otherwise, your citizens will succumb to either starvation or the elements and your city will fail. With so many moving parts to micro-manage, Banished is not an easy game to play.
The best advice I can give for now is that you shouldn't expand too fast. I tried to get far too many professions going at once and ended up crashing my population 20 years into my first game when the food reserves ran out. The village never recovered from the initial drop in population, mainly since I foolishly shuffled folks from wood chopping to food gathering. People started freezing to death the next year.
This eventually left poor Damiah, the 57 year old builder, as the last resident of the village. I let him live out his final days picking pears from the orchard and eating to his heart's content. He finally died at 63.
Although I have yet to master it yet, I'm still having a ton of fun with Banished. If you like SimCity, the game might just be for you, but if you're looking for something that involves less direct management and has more of a reliance on urban planning, then Banished might disappoint you. Still, at about $20, what have you got to lose?
