Actually, I took that logo straight from a screen shot in Wing Commander 2 and traced over it. Its a lower case i. I was kind of surprised too. The logo is the one not at the selection screen but at the beginning of the game after that in the intro sequence. Watch the video of it if you don't believe me. Like I said it looked wierd to me too at first and personally I kind of like it better with the lower case i for some reason.
The reason I selected that version of the logo and not the one at the selection screen is that this one is the one I always remember when I think of Wing Commander 2 so it was the one I wanted to do and it took me awhile to get it right because my computer for some reason screws up screen shot directly taken from the game. So, I had to take it from the video that we have on the site that I forgot about till the other day.
