So, I installed ArcheAge Korea and have been playing it off and on for a week. I am level 27. First impressions:
1. Atmosphere/Graphics/Artistic Direction are unparalleled and by far the best feature of the game.
2. The games attention to detail is amazing (rivers have currents, interactive objects everywhere, etc.)
3. Combat is tab target style, feels mediocre but serviceable.
4. Questing is standard quest hub progression. It isn't very grindy and they move you through the world pretty rapidly, allowing the atmosphere to carry the experience.
I am in an English speaking guild, so I hear a lot about the end game features, but haven't really experienced it. From what I can tell from speaking to people that I trust not to over-hype or bullshit, the overall "flow" of the PvP end game goes like this:
(a) People grow (simple mini-game basically) or collect (standard mmo stuff), or steal from others that grow or collect (same faction or cross faction), bulk resources.
(b) NPCs in +PvP areas where instant access options (ie teleport) are limited give you badges for end game gear and gold for bulk resources.
(c) To efficiently move large amounts of resources, you need a cart, donkey, pack, or ship.
(d) You can loot people's carts, donkeys, packs and ships in PvP.
So basically, they give you a reason to aggregate and transport resources, then allow you to kill each other for those resources. I haven't actually experienced this part of the game, so I will update this post when I do, but that is the overall concept as to "why would I PvP." The rest of the systems (criminal system, pirate system, etc.) center around that overall concept. Additionally, at the higher end, there are non-instanced world bosses EverQuest style, so racing to get spawns, protecting spawns, etc is a significant "indirect" PvP incentive.
Overall, its a really enjoyable experience so far....carried largely by the atmosphere of the world and artistic direction of the game. Also, the "what's next" feel of the feature set is very compelling. The farming mini-game, gliders, mounts, and battle pet systems are fun sub-components of the game that I have experienced already before level 25 and really break up the ordinary leveling experience with something new and interesting. It's worth the purchase so far. At a minimum, I will get one character from each faction to end game to see what it is like.
