I finished all of Raiden's VR missions last night and it made me wonder if I ever actually did that the first time around, I'm pretty lazy and they're quite difficult. I can't lie, I gave up on getting the top times quickly, but managed to do Raiden X's single mission (which is to do five missions in a row) the second time around and it definitely didn't feel familiar, but it has been like 20 years.
Probably going to grind out more dog tags before I start on Snake's missions, honestly. I've done all the Snake Tales and have all the tanker tags on very easy, normal and hard. I wonder how far I'll get before I give up.
