obSESSION Cross-Genre Roleplaying BETA

The obSESSION Beta Edition is a release designed to be used to playtest and improve the system before it's full commercial release.

This Beta Edition contains

• The final release Core Rulebook, complete and ready to use
• Samples from the forthcoming Simple Fantasy genre supplement
• An "Extras" booklet containing additional material

Purchase of the Beta Edition will entitle you to receive the Core Set when it is released, including the full versions of the Appendices. Over the course of the remaining development the Beta Edition will be revised to gradually bring it closer to the final Core Set. This will involve both the addition of the Appendix material and the removal of the "Extras" and the samples, though some material which originally surfaces in Extras will likely end up in the Appendices.

obSESSION is more than just a Role Playing Game, it is a set of core mechanics designed for use with any setting, genre or game style. The fully expandable rules contained in this book are adjustable for a variety of playing styles and can be used to model any reality that the GM or designer can imagine.
Additional optional rules from Obsessive Compulsive Design are fully compatible with the rules found within, expanding upon rather than contradicting the core rules and ensuring that any optional expansion is usable with any obSESSION game, not just one or two.
GMs and designers can choose the level of realism they desire and balance it against a number of player-friendly options to create the game and experience that they want. By building from a consistent base model of reality obSESSION allows for the rules or settings to be “tweaked” without losing compatibility. It’s internal consistency also allows for a minimum of mechanics to cover a maximum array of potential situations and makes “on-the-fly” rules decisions simple.

The Core Rulebook contains enough to begin using the obSESSION system with a little work from the GM but these rules are expanded upon and complemented by the material found in the Appendices. Optional, alternate and advanced rules make obSESSION adaptable enough to fit what YOU want from a game, whether for your home campaign or a planned publishing project.
