If cases are equivalent to prepositions, why do the IE languages have so many of them, yet look with wonder on Finnish with its bunch? Anyway, continuing the idea of 3 core cases for, approximately, nominative accusative dative, there are 3 more common obliques, genitive ablative locative. But then they start splitting into infinite sub-types, or until exhausting patience. There one can start using verbs like "concerning". At this point, since my conlang had only, effectively, 2 core cases plus a genitive, I left it: no prepositions at all, just serial verbs and participles. I think it really does "work", but I feel uneasy about it.
