Uh? I love MGS2 and Raiden's MGS2. But yes, I don't accept that everyone can become like Snake, no way. Again, Raiden had a purpose and they achieved the result, but it's one case and one only.
I really want to see how a random medic can live up to the great Big Boss and even feed his myth. Hopefully it's not like
"ehi dude, you're Big Boss"
"who?"
"the greatest soldier ever lived"
"oh ok. Yeah I kinda feel like that now that you mention it"
Basically the same boat I'm in. And unless the coma thing is all a ruse as well (which it doesn't appear to be based on the hospital gameplay where the character is weak with atrophied muscles), I'm not sure exactly how he would be been trained sufficiently to take over for Big Boss in the first place. The Boss, Big Boss, his clones, and MGS2 Raiden (due to
extensive reenactment training made possible through top of the line futuristic VR decades later) are part of a legacy of top tier "supersoldiers" throughout the series.
And now we're learning that a comatose buddy, who isn't even a career fighter, is able to completely and flawlessly take over for Big Boss, not only for morale purposes around the base, but also as someone capable of soloing field ops just like the legend?
It would have been more believable if it were Ocelot, who was at least The Boss's own son and a warrior with years of experience both on his own and with Big Boss. Obviously more plot holes would be created, but it's not like the series isn't wacky enough already.
