I have been wanting to do a PUArcade site... have it running on my home test bed box, but not really done much with it...
The only suggestion I have is due to the size of my monitor - 1680x1050... the games are all floating to the left, I think centering them would look a lot better.
Yeah - the right column stuff pushes everything over and it is really more of a revenue issue than a design one.....but one I am solving. Once the right column goes away I think everything will line up nicely....stay tuned!
PUArcade is great - but a bit restrictive.....at least in the larger arcade world. I have done a bunch of hacks and changes - and working on ten times as many! So if you get around to starting one and need some help - let me know!
