TAG 1 and 2- Marathon vibes?

[Taurus Daggerknight]

So here's something I've been wondering since Tag 1, but REALLY felt it in TAG 2; 

 

Was anyone else getting a little bit of Marathon 2 in the whole thing?

 

Mostly TATG 2's environments had me feeling this, but really... Immora kept making me think of the cities in the skylines of Marathon 2's early levels, and the outdoor segments of the World Spear kept making me think of Halo. Not the medieval town mind, the outer-wilderness areas.

 

I'm not saying any of this in a bad way, other than a vague notion of "is it Doom", because it all looked gorgeous and all that. I'm just wondering if I'm the only one who kept recalling the Bungie classics here.

I was kind of getting Serious Sam vibes from the opening level of TAG2. Probably because that's the only FPS series I remember playing which has action-packed shooty shooty bang bang taking place within a brightly verdant landscape.
