Yeah, at some stage you realise all the generic missions have like three floor plans they cycle between and it gets boring.
That being said, I think the Citadel layout in 1 was by far the best. It actually felt like a 3D maze with a seedy underbelly and a rich upper crust, unlike the three halls of 2 and the disjointed sections of 3
Daaaamn, were people cosplaying their favourite Jules Verne character or something?
