I would definitely like to play in the beta for a few reasons.
1.) I am not too interested in any other games right now. I'm not really buying any other games because I am saving up for a new PC, a trip (probably) overseas, new work clothes. So I've been replaying old games and really just waiting for FFXIV. The sooner I have a new game to play the better.
2.) I don't have much time to play, and for that reason I would like to play in the beta. I feel like I can take my time exploring the areas and testing for any problems, rather than feeling pressure to level up or find groups. The idea of a character whipe doesn't bother me, and, because of that, I wouldn't mind playing in the beta.
3.) It sort of feels like a sneak peak. I guess I get satisfaction out of saying to myself "Wow, I'm one of the few folks who are getting to see this!"
4.) In two of the three betas I participated in the customer service was a lot better and GMs were much more responsive to problems. There are more problems with the game but they get fixed quickly. Unfortunately, in the past few games I've played, once the game goes live GMs stop really caring as much after a few weeks. Sometimes it takes months to fix a problem and when something bad happens to someone that is the fault of a developer nothing is really done.
For example, a player is stuck. GM comes out, frees the player, and writes a report. No one is stuck in that place again.
Once the game is out of beta: Player is stuck - calls a GM. Waits...GM arrives 10 minutes later. GM frees player (in some cases I've had GMs appear, say nothing, and leave without solving the problem), GM was going to write up a report but doesn't.
Hundreds more players get stuck. 2 months later the problem is fixed.
That's one reason I like betas...better customer service.
Some reasons I don't like betas:
1.) Many players will apply for the beta with no interest in finding problems, following instructions, or reporting flaws. Therefore, less problems are fixed.
I would like to see a system where players are rewarded for finding faults in the game and reporting them.
2.) Many players sign up for beta without realizing there will be a character wipe. When they find out they shout and curse.
Or players, knowing there will be a wipe, sign up anyway and then complain about the wipe regardless.
3.) Players who sign up and play without understand what it means to be a 'beta' version and continually complain to other players about every problem they encounter but never report it.
Anyway, yes, I would very much like to participate in the beta and help prepare the game for the retail release.
Toasting makes me uncomfortable. But toast I love. Never start the day without a good piece of toast. In fact, let's toast to toast.
