My favorite systems, though I am not too familiar with many, are the ones that offer the most customization. Magic with a drawback has always been my favorite game mechanic, which is why Deadlands has been one of my favorite games (and setting!) Skill-based games like Shadowrun and Deadlands are great for me, fantastic settings and systems. I have ever played. Pathfinder, D&D 3.5, Vampire LARP & Tabletop, Deadlands, BESM, Star Wars (the Newest edition), that one WWII Superheroes Game, Serenity, etc...are all great systems that I would enjoy playing again.
