I've dumped a bazzilion PDFs on my Kindle DX at this point. Ok, maybe closer to 2 dozen, but have a bazzilion on my hard drive that have yet to make the transition. So, how do they look so far? Here's my totally nonscientific opinions on a scale of 1 to 5.
Elric - Runequest/Mongoose Edition - While readable, the font is small (even horizontally)and and the background clutter isn't helpful. 2
OSRIC 2.0 - Clear, uncluttered pages. This is what a PDF should look like on the Kindle DX. I can read it without turning it horizontally. Could have been made for the DX. 5
HARP Lite - Clear pages with no distracting background behind the letters. Artwork in the margins converts well. This and its sibling Rolemaster are table intensive and they look perfect. 5
True20 Quick Start Rules - Clean and uncluttered. Font seems a bit smaller then others, but looks very nice when viewed horizontally. 4
Kobold Quarterly #8 - This PDF converts exceptionally well. I may no longer need to subscribe to both print and PDF anymore ;) 5
Points of Light Campaign Setting - Goodman Games - I'm not sure if its the light watermark art behind each page or if the font is smaller or both, but it isnt as easy to read as it could be. Held horizontal it looks much nicer. 3
I'll add to this list later. Remember, I'm just rating these PDFs on their suitability to be read on the Kindle DX. I'm not rating their value or worth as gaming products. That being said OSRIC is an amazing value and available for the unheard of price of FREE! Kobold Quarterly is what Dragon was back in the day with modern typsetting, making it a valauble addition to any gamers library.
