Guys, stop arguing. This is the right forum because it's a suggestion for the maps, but it's also the wrong forum because it's a suggestion for the map, not a map idea. It really doesn't matter, stop flaming that this is the wrong topic and keep the thread on topic.
I like the idea of the villager shops, except that it can't be for any weapons or better than leather armour. Maybe you can trade for any tools other than axe and sword (still can't break blocks though). You can also trade for food. Otherwise it would be too easy to get weapons and armour and therefore win the game.
