No, I don't know that much about fonts. I know what kerning is from having to change it in Photoshop a few times in the past, but yeah, I've never made a font or anything. About TDM's fonts, the one thing I remember strongly is the handwritten "t" that looks like it has an actual space character in front of it. Off the top of my head I can't think of any other glaring error that really bothered me (I complained about one font being hard for me to read, but that's simply because it was heavily handwritten and I have a bit of a hard time reading that even in real life ) From a player's perspective, the kerning looks like a sort of "polish issue", like the first thing I thought was that somebody made a nice font and simply hadn't gotten around to tweaking it just right. And I assumed "okay, work in progress, it'll probably be fixed eventually". I say it should be fixed at some point or other, because it's the little "off things" that are all the more noticeable the more polished everything else gets (that font is otherwise very nice, for instance). I don't know, I hesitate to call it a critical issue or anything, but it's still a bit bothersome *shrug* Very cool. I tend to speak my mind and then feel bad about it, but people often tell me it's helpful, so I guess it works out.
