Today kicks off a week long promotion over at DriveThruRPG where several of the top selling Old School Renaissance (OSR) products have been put into the spotlight. In addition to highlighting some of the best selling products they are offering a 15% off discount (OSRF711F2) until Sunday, May 19th.

There are several great products available. I have been dabbling a fair amount in the various OSR sources so I see several that I have already been having a lot of fun with.

The Castles & Crusades Players Handbook is on the list. Castles & Crusades is an excellent blend of old school sensibilities with more modern mechanics. This is an excellent system to start with for someone looking to experiment with an OSR gaming experience. Transitioning from a system like Pathfinder or D&D 3.5 is quite natural as the core mechanics are similar enough, but streamlined enough to give you a great OSR experience with minimal relearning of rules.

Dungeon Crawl Classics RPG also made the list. This product from Goodman Games gives you that old school feel with a new set of mechanics. Random tables to roll on for spells, new flavor to existing character classes, and the use of a 0-level funnel for new characters brings a fun experience to the table. I have been playing this game weekly since about July of last year and we have been having a great time with this system. The artwork alone in the tome is worth the price of admission, but you will stay for the fun.

My latest interest is also on the list, Swords & Wizardry Complete. A retroclone of the 0e D&D ruleset, S&W gives the OSR player a solid foundation to work from. Just the bare necessity of rules that have a true D&D feel. This system is soon becoming my favorite as it provides me with what I need and gets out of the way. When I want to house rule certain areas it makes it easy to do so as I am much less likely to contradict something in the base rules. There is also a very strong community behind S&W on Google+.

There are several other great systems on the list beyond the ones I highlighted. Swing by DriveThruRPG and take a look. Don’t forget the 15% off code: OSRF711F2
