I'm playing Forbidden Lands and I use generators provided with the GMG (very helpful) as well as official solo rules included with one of the supplement books
apart from the usual yes/no and themes oracles included in the later I find setting-specific factions oracle to be pretty handy

also technically you don't really NEED anything beyond yes/no + theme oracle
but having other question specific oracles really helps even if those could have been reduced to the former
sometimes just glancing at tables and what kind of questions they answer is helpful as a reminder for possibility to explore

for example friendly/hostile oracle is basically a yes/no oracle
however simply having this table reminds me to ask this question and often leads to exciting developments
were it not there for me to see while flipping the pages, I would probably forget to ask this question and just assume the path of least resistance (friendly)
