The Ramanujan behavior is typically explained by the fact that the imaginary quadratic field $\mathbb{Q}(\sqrt{-163})$ has class number one (together with an integrality property of the j-function). Since there are only finitely many such imaginary quadratic fields, you can't really expect to have infinitely many similar phenomena (at least admitting the same explanation).
