Another bundle offer that I don't know much about and (to be honest) probably isn't of much interest to me:

" the lavish Old West RPG from Kenzer & Company. Aces & Eights is an inventive and lavishly produced sandbox game with many interesting rules systems. Though it's set in an alternate 1850s timeline (the Civil War happened early and the South won), there is no fantasy element; the setting aims for realism."

PLAYER'S COLLECTION (US$8.95 - retail value $45)

• Aces & Eights: Player's Guidebook (retail $15)
• Showdown ($10)
• Shootist's Guide ($15)
• Bad Day at Buena Roca ($5)

GAMEMASTER'S COLLECTION (threshold starts at $19.95 - retail value $55)

• Gamemaster's Addendum ($5)
• Rustlers & Townsfolk ($15)
• Judas Crossing ($20)
• Rustlers & Townsfolk: Judas Crossing edition ($15)

All are DRM-free PDFs. As usual there's going to be at least one extra item for the GM collection, to be announced later. The way this works is that the earlier you buy the GM's collection the cheaper it is - no matter when you buy it, you will get all bonus items.

Ten percent of each purchase (after gateway fees) goes to the Electronic Frontier Foundation.

Usual caveat - The main reason I know about this offer is because I'm on the list to get this stuff free if I want it. In this case I'm not very interested, but I think it's a reasonable deal. If I think these are bad deals I'll say so.
