If I could evaluate UNPUBLISHED choices, I would not be posting here. I would hitting Vegas betting with the knowledge on the UNPUBLISHED choices. Then buying a mansion and a yacht! I find your post totally silly.
Are you suggesting that there aren't people out there already deciding whether or not to play D&DN based on the information that's available right now?
Balesir makes a great point. Some people, (my wife for instance) are easily paralyzed by too many options. She has the feeling that if she hasn't thoroughly evaluated every option, then how can she make an informed decision and not feel buyer's remorse for her selection? In her case, opening up a wide-open field of options is not a good thing. She fits the mold of exactly the kind of person that the study referred to above is talking about.
Me, on the other hand, I'm a much more decisive personality in general. I'm ready to leap into action and consider a decision made based on a quick and dirty executive summary of a handful of options that are immediately in front of me, and I rarely look back and question my decisions already made unless 1) it's obviously not working out and a new decision needs to be made, or 2) new information becomes available to me that I didn't know when I made the prior decision.
For personalities like mine, that study is complete nonsense. I don't feel the need to research every option available; I'm perfectly happy making a decision based on the options that are immediately in front of me
only. Plus, making decisions is easy, and not based on painstaking research ahead of time. Plus, I can evaluate almost subconsciously how much I'm going to like a given option ahead of time quite easily, so I feel confident in my decisions, even without lots of research. For me, having lots of options is empowering, not paralyzing.
I'm sure that the range of human responses is a wide spectrum between those two relatively extreme positions (not that I wife and I are truly on polar opposites of this spectrum; rather than she trends one way and I trend the other).
But by and large, having more options is
always better. I've never heard anyone complain before that they have too many options of shows to watch on TV and therefore are paralyzed by indecision and don't watch anything. Same thing with books to read, video games to play, or vacations to take. I don't know why role-playing games would be any different in this regard than any other form of leisure time pursuit.
