I echo Waveryder's statement's a little bit. The font choice doesn't bother me, I think that the forums do make the edges rougher at the smaller size, but it is in a similar vein to the original Playchoice font, whether exact or not. But I do not think the gradient works as is just in the respect that it looks like you dragged the gradient tool straight up and down, when the text is on an angle, hence getting the black only in the lower left of the text.
But all that is null and void with the main issue I see here, too many things competing for attention. The Pretendo logo is too big, and I think the Daniel logo is too. The marquee will be huge, so remember, a small Daniel logo on screen here will still be big in the print. In this instance, it will be huge.
Why not more closely replicate the original marquee, and this is where I would open to your argument. The why's. I love the idea....6000 choices, very original actually instead of these marquees you see all the time with either fire or lightning in them. Yeah, we get it, your mame machine is the baddest and most original of them all. But why not make the marquee look exactly like the PC10 marquee, same red line placement, you can apparently get the same font from Waveryder, and keep the text italicized but on the horizontal axis. I think the seal is cute, but I would drop it...doesn't add anything...and maybe you're concerned with the 6000 fitting in the place of the orignal "10", but I bet if you scale it down just a touch it would fit in one line. If not, you could still use your original idea of having it underneath on the right.
Either way, most of the people playing your system wont' know PC10, but true collectors who know it will probably appreciate your work more if you make it look really close to the original, but take your own personal idea and modify it.
