I have stolen this idea from Brian’s weekend round up. I think the answer is an emphatic yes to Low Fantasy; especially RM2/RMC when played with the core rules and no options.
Why core only? The first one is magic. The actual base ruling on spell list acquisition is in RM2 and RMC is D100 + ranks in the list. Roll 101+and you learn the list. You can learn only one list at a time unless you buy 20 ranks in the first list and then start to learn a second. If you fail to learn a list you can carry those ranks over to the next level and continue learning that list or you can lose all those ranks and try and learn a different list. You will note that there are no bonuses to that spell list acquisition roll, no level bonuses, no stat bonuses.
