The good folks at Sine Nomine are ingenius. So much content was provided with the Free edition... that you might ask... "Why would I pay for the full version? Why would I buy the print version?"
That's the brilliance... the free edition gives you so much meat... but it isn't the full feast provided by the full version.
The system is relatively simple... a flash back to the bygone eras of the boxed editions... but with a twist... same stats... the usual 6... generated by rolling 3d6. But now... throw in skills, backgrounds...
Character classes are Expert (aka Rogue), Warrior (Fighter), Psychic (or Mage) and Adventurer (think "Jack of all trades" you can be a Warrior/Expert or Warrior/Mage... you get the idea...)
Skills... lots of skills.
Foci (think "feats")
Best of all... the GM Section... build worlds... build empires... build factions...The GM section alone is a gold
mine of ideas, hints, tricks, etc to really make the game your own.
After getting the Free edition PDF... I knew I needed the print version... and it is worth it. The art... the additional components... space magic... yes... space magic. Battle mechs... starships... build alien races and societies...
And it is all compatible with Worlds without Number.
And with very little effort... you can bring modules from pre-3rd edition D&D...
The GM resources section is very system agnostic as well...
Like Chaosium's BRP? The resources transfer... with little effort.
Want to fight the cult of the Space Reptile God? This is the tool kit to make it happen...
Want "Space Elves?" You got it.
Want to build space monsters and creepy crawlies? You got it.
But do not ignore the elegent simplicity of the Sine Nomine system. It is deceptively simple.
All this being said... the quality of the PRINTED product is second to none.
