You're old fashioned.
I still love RM2. Not RMC. Just plain old RM2. My kids are all hooked on it now, my now ex-wife, and just a few months ago, three, possibly four new players really into it.
RMSS had some great ideas and refinements that I really liked, but too much of a departure from what I loved but not enough to get me to re-invest all that time and money into a "similar" game system. (I have all of the RM Companions. I'm an addict. What can I say?) It wasn't like going from RM2 to White Wolf or D20. It was still RM, just different.
I have an open mind and anticipation for RMU, but still not sure it will be enough to get me to leap from RM2.
I think the only major mod we ever did to RM2 was the initiative system. We simplified it down to just open ended D100+QU bonus. Everyone went in order or held their initiative until the wanted to act to interrupt someone.
Quellbourne is still one of my favorite companions. Just saying
