I wasn't aware of the game, but the inscription (and yes, it is Latin) means (more or less, it's been forty years):

una infinitas
One forever

abominatio nascitur autumno
An evil is born in the fall

hic est tuum temptamen quod temptat tua potentia
this is your [attempt to test] your power

viginti tres gradus ad summam potestatem
[There are] three levels to the highest power
