Also, it is best to get a visual comparison between fonts if possible (e.g. There have been questions about free alternatives to Helvetica and also similar fonts to Helvetica Neue, but the answers were based on available fonts from at least a couple years ago and I would like to know if there have been changes or new fonts since.
This was the response, Michael Lai gave me: I (Ryan, whom is editing this) asked what is meant by dated. Please include a visual example if possible, and include some reasons why each font would be a good choice I'm after a smallish number of well-thought-out suggestions, and definitely not a bare list. a single story 'a' or distinctly different 'g'.
I guess I'm looking for something that will be a close match in most of its shapes but will have enough points of difference to make people (OK, other designers) wonder what I've used. I'd like to use something similar-but-different for my poster project.
