Usually I am always in a guild in any game I play. If I am new to the game, I go to a casual laid back guild just to chat with people in game and make some friends and get some help quickly. If I play the game long enough, I might go to another guild that is more challenging or even seek to have a higher rank in my current guild. Sometimes, I read the guild announcements posted by the guild leaders and hang out with the guildies when they are up to something fun.
How about everyone else? What do you guys do in your guilds? What aspect of being in a guild do you enjoy the most? Is there anything that games should include to make guilds better?
The only times I find it hard is when you have to donate in-game currency just to have some sort of "status" in a guild.
