  We study the product $P_m$ of $m$ real Ginibre matrices with Gaussian
elements of size $N$, which has received renewed interest recently. Its
eigenvalues, which are either real or come in complex conjugate pairs, become
all real with probability one when $m\to\infty$ at fixed $N$. In this regime
the statistics becomes deterministic and the Lyapunov spectrum has been derived
long ago. On the other hand, when $N\to\infty$ and $m$ is fixed, it can be
expected that away from the origin the same local statistics as for a single
real Ginibre ensemble at $m=1$ prevails. Inspired by analogous findings for
products of complex Ginibre matrices, we introduce a critical scaling regime
when the two parameters are proportional, $m=\alpha N$. We derive the expected
number, variance and rescaled density of real eigenvalues in this critical
regime. This allows us to interpolate between previous recent results in the
above mentioned limits when $\alpha\to\infty$ and $\alpha\to0$, respectively.
