OK mine at the time was RQII, I really didn't like RQ3 when it came out.
In hindsight I think RQ3 was a better system,.
Reasons for not liking RQ3 at that start were,
Not being glorantha based - especially bloody awful games workshop version
Bloody awful scenarios and supplements - Compared to Borderlands, Griffin Mountain, Pavis & Big Rubble & Trollpack, Cults of Terror and Cults of Prax
No blade venom rules
Spirit magic not always working
No decent cult write ups
Medievil west
Reason I converted over time
RQ3 Renaissance stuff was excellent
The systems more subtle
The system seems more logically consistent
RQ2 mechanics started to date and seem clunky
It gave a wider sense of Glorantha
