I hated guild wars....for the first 20 minutes I owned it. Now I play it all the time. It's great, and they come out with a new one every 6-8 months (6 I think). Even the original game still has a ton of players on it at any given time.
There's a series of characters you can choose from, each having their own skills/spells. Then, you can choose a secondary profession and use their skills/spells. It's nice, because you can be a warrior/ranger and really tear some stuff up, or be a monk/warrior and heal others while defending yourself, or be a elementalist(fire magician so to speak)/monk to take advantage of the higher energy capacity to expand your healing abilities, or....you get the idea. In the first guild wars, there's 4 characters, then when factions came out they added 2 more, then when nightfall came out they added yet another 2!
The game has it's own economy where you sell things to make money, but next week it'll be a lot cheaper or worth nothing at all! Of course their's armor to upgrade, upgrades to your armor, loads of weapons, off hand items etc. etc. etc. You can run around and do missions/quests, or do faction battles or do guild battles (you need to be in an active guild to do so).
It's always nice to have someone to help you along when you start out, but there's usually enough people online to help if you need it.
You can pm me if you get it and I'll help you out if you need it
War produces veterans, wounded both physically and mentally. They have sacrificed for us.....and it is now our job to help these veterans, as they have already helped us in ways we will never know, in ways that we cannot fathom, and in ways that we take granted every day.
