If you haven't seen any of XRP's "Seeds" range, download the free Fantasy Seeds PDF, as they all follow the same format. The ZIP file includes both Print & Screen versions of the PDF.
These are exactly what the name suggests - barebones adventure seeds for GMs to build upon. They range from simple one liners "The PCs are car-jacked", to quite detailed and convoluted plots, but they almost all leave the ultimate resolutions to the GM.
These are all aimed at the modern day real world, without any major FX powers (although some have a hint of weirdness about them). Many of the ideas could easily be adapted to other genres.<br><br><b>LIKED</b>: Inexpensive, well laid out.<br><br><b>DISLIKED</b>: There are a couple of seeds that don't don't read very clearly, as if written by someone with English as a second language. Since the seeds themselves are from a range of contributors this might well be the case, but XRP ought to have edited these for clarity.<br><br><b>QUALITY</b>: Very Good<br><br><b>VALUE</b>: Very Satisfied<br>
