Hi! Great system! How do player vs. player actions get resolved? For example, player A tries to tackle player B...or player A tries to hide from player B? Highest roll under Feat rating or ??? Please advise - thank you...

Hi it's Brian again - the publisher got back to me via my email and let me know that in combat, player vs. player works the same as player vs. npc. For non-combat activities, whichever player rolls lowest wins. I like this system...very elegant!

Thanks again Brian for the great question. Just posting the text from my email. Combat is handled the same as PC/NPC.

For non-combat rolls, the lowest successful roll wins. As an example, if two characters are in a foot race, the GM would typically assign the same ODDS (e.g. 50%) to both. The character who has the lowest successful roll wins.

So if John rolled a 21 and Jim rolled a 34, both are successful but John crosses the finish line first. If by chance, they roll the exact same then it is a tie. In a foot race, there is going to be a winner so if both fail, then re-roll until someone succeeds.

In some situations, if both characters fail, then maybe no-one succeeds. For example, If both characters are trying to find an object and fail their Scavenging roll, then nobody finds it.

In some cases, you should make one character's roll contingent on the success of the other. For example, if one character is trying to hide from another. If you ask one to make...See more

Thanks David! Was wondering if the character sheets could use a few 'empty' slots for write-in Feats. For example, ride/drive/pilot is not one of the 18 standard Feats, but could be something a player-character would like to have, with GM's approval. Having a few blank lines for write-in Feats would be nice (although it's easy enough to write them in on the margins or whatnot).

Hey Brian. Thanks again for the recommendation. I've upgraded the generic character sheet to provide three extra lines for other FEATS. Your mention of the Drive FEAT reminded me of something. The FEATs can be very different depending on the One-Shot. If you look at the LAST REICHSRITTER sheet, you will see Drive is there because the characters have an opportunity to drive a tank. This is my first release of the rules - now I'm thinking I'll create different versions based on the genre (e.g. medieval, modern, future, etc).

File Size:

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
