*Pulls up chair* "I'm Chezen Lightbreak and I am a solo player."
First off, there has been some really nice replies here from all sides. I want to thank everyone who has presented their view in a calm way without purposely insulting anyone (in a subject like this, some accidental ones are bound to come up). I will try to do the same.
Recently, I saw a similar thread about soloing in Rift. The OP was actually rather obnoxious, although his points were generally true, and I expected him to get flamed to the ground. But to my surprise, there were some very sincere replies to it, just like this one, many of which are being echoed here. Solo players aren't a small minority any more. They are growing, rapidly. Interestingly enough, one of the most common replies in that thread, but barely been mentioned in this one, was that many used to group, but got fed up with the (I use the term often used in that thread) "jerks". The irony that people became "antisocial" soloists because of players who don't know how to socialize, didn't escape me.
However, despite the mmo part of an mmorpg, solo players still like to play mmos, effectively debunking the standard "anti-social" stigma. Someone truly as anti-social as the stigma implies wouldn't play an mmo. And yet, I'll even offer for debate, that there are plenty of "social" people who are effectively far more anti-social than many soloers.
What is a community? I think of community as being a group of individuals who share a common sense of concern for the wellbeing of the group in their area, in this case, servers or cities. Some within a community will be more independent than others. Just because they prefer to contribute in a more solitary way, doesn't mean they do not contribute. I think FFXIV has the foundational build to allow a community that can participate in whatever way suits the individual.
The key is... solo, casual, and hardcore play should not interfere with each other. But at the same time, in order to maintain community, they should not be entirely separate from each other either. Crafting, as already brought up in the thread, is one way to accomplish this. I actually loved how detailed each crafting piece was (I'm aware they are downsizing), because I saw how it could either make the community depend on each other, or at least, make a soloer work very hard for his independence, which is as it should be. If you are going to do it on your own, it should be a little harder to do, imo. (This doesn't mean I think there shouldn't be soloable battle content, but as was also stated in the thread, don't overnerf it. Of course, easy and hard varies to the individual.) With the companies and class and job changes coming out, I think there some unique opportunities to have both separate and interacting solo and party missions, should SE seize the idea.
For my own part, my reasons for soloing are many, and both simple and complicated. Many are mentioned in the thread, such as uncomfortable LS conversations, liking to do things myself and on my own time, having to leave at any given moment, etc, etc.
Other reasons... I do enjoy being on my own. I am introverted by nature, meaning I enjoy keeping to myself. It doesn't mean I don't enjoy interaction. As one person stated, more or less, in the Rift thread I mentioned, "An extrovert will enjoy solitude for a time, then go socialize to recharge. An introvert will enjoy socializing for a time, and then go find solitude to recharge." That is me. It is difficult to find people who really understand that. They are offended by the idea that I might not actually want to be in their company every time I log on. I never really want to offend anybody, and I would feel bad if I hurt someone's feelings, although in my old age I'm getting less concerned about that. I guess I came to a point that I thought my feelings should count for something too.
The most important reason is the most personal, and that is... I was part of a group once. A very close-knit group of very good people who either understood or at least tolerated my introversive ways. But even good people, through no real fault on their own, can find ways to hurt each other, and such things can end very, very painfully. We are all, in the end, different people, from different families, and different backgrounds. Maybe someday I might find myself in a permanent group again, but I'm in no hurry. I am honestly very happy in my own little niche of this game. I enjoy my character. I love guildleves. I love cutscenes. I love DoL activities. I tolerate crafting.Occasionally, I'll have some sort of interaction with people, and I love that too. Then when it's said and done, I'll go to my fun, and I'm happy.
(I'm really sorry for the book this became.)
