What was the last time you were harvesting a resource along with another player, and they got a level, and you said [Congrats!] (What was the last time you said ANYTHING to another person farming materials that wasn't a four-letter expletive?) Say what you like about the game's problems, and they're not trivial, but mining/logging/fishing/etc. are tremendously better in this game than in other MMOs. The items are limited by extraction time rather than by making the extraction points rare and competitive; I'd much rather play the little hot-cold minigame rather than spend half an hour running around looking for nodes, only to get beat to them by high-level players literally dropping from the sky onto them.
(It also means that, relatively speaking, resources are abundant. Yes, this means we're all feeling the inventory pinch more than we might otherwise, but I'd rather have to decide which pile of stuff I'd rather keep, if the other option is to have an empty bag! And yeah, even that will improve once we get the tools we need to get our surpluses into the hands of people who want them.)
The crafting system is a joy. It's complicated enough to be interesting - it's not just a matter of "lol gather this pile of materials, buy recipe x from vendor y, hit "craft repeatedly" until level zzz, go to step 44". It's got a lot of interesting interdependencies. (To be sure, that's annoying when hardly anyone on the server has critical jobs available. But even this early, I've made a lot of LS-members happy because I was the guy who had some glue or some dye or some rivets on hand... and their joy is often expressed in gil, which I ain't complaining about, no sah.)
I like the experience of crafting. I like how some recipes are just bloody time-consuming, so that even when there are level 40-50 crafters running around, I'm still going to be able to find stuff to craft - even once the market gets working, a handful of high-level crafters can't possibly fill all niches. I like being able to repair my stuff in the field (and my buddy's stuff too!) I like how I get some exp every time I craft something, even if I blow it.
That's why I'm enjoying the game, honestly. Yeah, as a marmot-killing simulator, it's pretty meh. The combat isn't as deep as some other MMOs. There's still some bugs that need to be worked out, the UI lag needs some serious love, and the market wards desperately need a search feature. A manual that actually told me how to play the game would have been a nice touch! But these are things that are getting in the way of the fun I'm having; I'd rather have it this way than to have a seamless, flawlessly-polished experience which just wasn't any fun.
Mind you, I'd love a seamless, flawlessly-polished experience on top of what I've got! But there's reason to have some hope there - SE's already made a couple changes to fix some nasty bugs, and at least one UI issue which was annoying me a lot has already had a fix put in (the craft window/chat thing). Clearly they're doing actual work on the game, not just keeping it in a holding pattern until the PS3 version hits.
