GW2 is so ridiculously awesome and addicting it's starting to negatively affect my health and social contacts
Seriously it's everything I hoped it would be.
It's also
very different from GW1, but in a good sense. I love how you can help people and get help from other players but the other players can never be annoying by killing your quest target or collecting an item you needed etc. even if you're not in a party together. Great to see how it works without monks/healer classes. The personal story element is great too, which is one of the few times where you play in instances and not with the other players (but you can play with a party if you want).
The fight system is a lot more active now, movement and dodging are very important, there are also more weapons to choose for the classes instead of just staff = mage, sword = warrior, etc.
Also I LOVE the event / task system, it is so much better than the traditional quest system. Especially the dynamic events, group events and huge boss fights that occur from time to time (pretty often actually, which is awesome). It's cool to begin a boss fight with only 2-3 people - or even alone - and then have other players rush there and join the battle because they got a notification. The crafting system is HUGE and very powerful, although a little complicated without reading something about it beforehand.
They also managed to make the whole world, dungeons, underwater regions (plenty! they're cool as fuck) and cities interesting and fun to discover. Very detailed, obviously created with a lot of care. I also like how you have to select some background options about your character, and often have different answering options and decisions in some of the quests - a little like Mass Effect / Dragon Age, though limited of course.
But what am I talking, you obviously can read the tests and watch Youtube Videos about the game. This is my personal game of the year for sure.
I'm playing a lvl 36 sylvari ranger and since yesterday also a lvl 10 human necro and I look forward to play other classes, races and choose other backgrounds to make sure I can experience all cool personal stories.
