As a developer, ensuring good game performance across a multitude of PC's must be a real headache and I'm sure an impossible task based on the sheer number of variants. You will always have someone encountering some kind of problem. Over at Tom's Hardware they've written up an absolutely fantastic graphics card and CPU performance guide, specific to Guild Wars 2. As someone who has always been fond of tweakguides.com this is probably the best equivalent.
I wrote an article some time ago about how Guild Wars 2 would fare when the critics finally wrote their opinions about it. Though not technically a community contribution, there are now 18 reviews over at Metacritic and well, it's doing bloody good.
A little cryptic but for anyone with experience of Dear Esther, I think you'll appreciate Ravious' latest entries...
Interactive maps are great. Interactive maps of Guild Wars 2 are even better with GW2Cartographers.com an absolutely wonderful tool. All it needs now is crafting nodes but I'm sure that's just a matter of time.
It isn't often that I find myself agreeing with criticism leveled at Guild Wars 2, but over at Techland they've written a list of 11 things and all of which I agree with. Some have already been fixed and I'm sure some are still pending but the biggest for me is not being able to see how long you have to queue for until you can play WvW. Surely this is a must?
I'm just clearing out Harathi Hinterlands and I'm unsure whether its a zone I'm enjoying or not. I can't quite put my finger on why, but perhaps the continued sight of Centaurs is having a lasting effect on me. Either way, I'll definitely support treasure seeking.
At Greibach's Normal Form he's written an epic post covering his time with Guild Wars 2 over a two week period, warts and all. I've personally been up to so much, I'm not sure I could even record it, although the low-light would have to be someone attempting to hack my account this morning. Luckily, AreaNet's email authenticator saved my account from the Tokyo hi-jacker.
Hunter's Insight has an article specific to servers, WvW pairings and guesting. My guild and several we were allied with decided to move from Ruins of Surmia very early on to Gandara simply to guarantee large numbers of players for events but also to find a greater presence in WvW. So far, it is working out but the landscape can quickly change.
Lastly, Reddit has a huge discussion about 'end game'. Perhaps the original author lacks subtlety, but he does have some very sensible things to say. In many ways this also ties into my reasoning of dungeon difficulty and that it should be kept as difficult as possible. Its surely got to be a good thing?
