If you are familiar with the Tolkien Universe ("The Hobbit" and "Lord of the Rings") you might enjoy The Lord of the Rings Online (LOTRO.)
TOG sponsors a LOTRO division
that has two guilds (kinships), one for the European members and the other for North America / Australia players.
Two comments to help you decide whether to check it out:
1 - It's been extremely popular since its launch more than 6 years ago and in terms of having stuff to do, it's huge. You can play one of the four Tolkien races (Dwarf, Elf, Hobbit or Human) and one of nine classes. (Note: You can also "roll" more than one character.) It's available in a F2P mode or paid subscription (which, if you *really* get into it, is actually cheaper.) There are tons of quests, solo content through large raids (24 people working together on a single goal), crafting, hobbies (fishing), all kinds of seasonal activities (Spring Festival, Farmer's Fair, and more) and even some silliness (like chicken session play) to keep you occupied for as long as you can sit in the chair. For some people it's become a primary means of socializing and the two kinships have spawned more than a few real life friendships. My wife and I have played it together since shortly after the launch and loved it.
2 - There's a major expansion coming out in about one month (mid-November) and it's got a lot of people very upset. The producer, Warner Brothers / Turbine, is overhauling the classes to the extent that people who've been playing the game for years feel like their favorite pet is dying. There may be some very negative vibes for a while. However, as a new player the overhaul wouldn't really affect you since you wouldn't be losing anything you'd built under the old system, meaning that might not be an issue for you.
If you are familiar with the story, as of the expansion it'll cover all of Middle-earth from The Shire to Rohan. Presumably over the next couple or three years it should include Gondor and ultimately let you participate in the final diversionary battle in front of the Black Gates.
If you decide to check it out, you can download the software from here
(be prepared for up to eight hours of downloading and installing ... like I said, it's a huge world and it takes time to get it into your computer) and you can join one of the two kinships by going here for European
or here for North America / Australia
. I suggest you start out F2P to see if it appeals, and if it does you can upgrade to subscription (about $13.00 a month which is cheaper if you pay quarterly or yearly) and that will remove the locks on F2P access.
Good luck on finding the right game to fulfill your entertainment needs. Who knows, maybe it'll be LOTRO.
