Notice that they were the same chords? Em and G are related (‘Relative Keys’). Just land on Em chord and it’ll sound like Em or keep coming back to G and it’ll sound like the key of G.
Here are some open chords in the family of Am (with the exception of the F chord) with a variation on the G (slightly different flavor, still G major though). Notice that in the key of Am, D is minor.
