Why doesn't AoM have a community as big as that of AoE?

I was introduced to AoM through AoE, but ever since then I loved both of them equally.

I always thought AoM was a much improved version over the massively popular AoE2 both in terms of gameplay as well as graphics.

Plus the introduction of myth units and godpowers increased the complexity of matches.

I don't understand how AoM doesn't have a bigger online community, while on the other hand AoE2 is still going strong.

Both of them got expansion pack and partial remastering of graphics, shouldn't AoM have more players online?!

Is it because AoM is too complex with god powers, myth units and Titans?!

Or is it because AoM MP games are too fast to satisfy many old school RTS games who prefer a slower 55 min base building match?!

Or is it because the developers didn't care about improving and promoting AoM as much as they did with AoE2HD?!
