Huh, cool... yeah, the dialogue is pretty sap-overloaded. I can also understand why Kojima would have wanted to end the series here.
(But lordy, after that ending message thing there's no way he couldn't continue. Also, I kinda figured that Solid Snake was the inferior clone, given that Liquid was able to pound me so hard =/)
On the other hand, despite only being able to compare MGS 1 and 4, I feel that the message at the end of 1 is surprisingly well followed up on in 4 (despite Snake not dying of FoxDie, but presumably his genetics). The character development seemed like it mostly went okay, too, though I gotta say that Otacon comes off like a completely different level of nerd between the two games. His VA was much more subtle in 1 than he ended up being in 4.
Ahhh, well. No matter. It was a great game, and in retrospect I really enjoyed every aspect of it. The bosses were clever and fun, and I approve of the emphasis on both Stinger and sniper rifle. It's really pretty danged brilliant. Even the side stories managed to tie everything together. There were honest twists I couldn't anticipate. Just enough character development that one ended up wanting a little bit more, and yet still extremely satisfying. Great music...
*sigh*
I really can't believe it took me so long to get off my bum and play this, because it's bloody amazing.
