A videogame magazine site would be awesome! I wish I had some time to pitch in. I have a number of PC Engine magazines from back in the day that I'd like to scan in (at least the covers).
It's been hard to find old magazines but recently luck paid off and I picked up a fairly large lot. Still been looking for mags that have previews of the PCE. I'm guessing Famitsu would be the best bet since it was the main gaming magazine back then.
