My first tabletop RPG was 1st ed. AD&D, then pursued 3rd ed. after that. After getting frustrated with the alignment system and the lack of creativity in the system, I over the years moved on to different systems such as White Wolf, Rifts, d10 keep system, and so on. So far my most favorite systems are the d6 keep system that Green Ronin uses, the d10 keep system that companies like AEG and White Wolf uses, and the Tri-Stat system that games suck as Hong Kong Action Theatre! (yes, it actually exists and it's awesome!) uses. I'm currently running a Game of Thrones campaign that Green Ronin publishes and is a great system for those that love creativity.
