RA2 definitely had some quality cut scenes, but Kane with the Brotherhood of Nod and whoever that suit from the GDI was were both pretty awesome too. That was my first jump from soley video game graphics to something more immersive. Online play though, RA2 was the best, especially p2p with my friends on nurple maps.
I wouldn’t imagine it’d play a role in reproducing though. It may help ones ability to live longer, but they have probably procreated long before tooth loss has become a major issue of well being or mortality.
