XL Games' forthcoming ArcheAge sandbox, you'll want to check out the third and final part of ArcheAge-Online's extensive CBT3 review.
The piece has a detailed breakdown on the game's labor point system (a third point pool, if you will, much like more traditional health and mana pools). Labor points are somewhat scarce despite regenerating over time, and most of the game's non-combat activities require them (harvesting apples from apple trees, chopping down said trees, building furniture and boats, etc.). It's a unique system, and ArcheAge-Online goes into the nitty gritty of the mechanics and offers up plenty of opinion as well.
The review also features commentary and video footage on sailing and nautical exploration, with interesting tidbits about boat construction and the discovery of player settlements on uncharted islands off the beaten path. Head to ArcheAge-Online for more.
