@ Tsel:
Notwithstanding the fact that Stone is a very proficient and knowledgeable 'Gothican' I have a differing opinion on playing G2 first and NotR separately thereafter.
Levelbalancing and somewhat increased difficulty set aside (not unsurmountable, just more challenging, and requiring more pre-meditation and cunning plans), the story and the locations of NotR are so much intertwined with G2 (you have to start all over in any case), thereby expanding both story and geography tremendously, that I recommend to give it a serious try, rather than having to adapt the methods and tactics you're getting used to from the older part to the expanded version.
