To been honest it was good when it came out but after playing a lot of better games it simply doesn't hold up and you will see that in its gameplay.get it if you really want but be warned you probably wont play it more than twice if even that. Id really suggest you wait for the hd mgs collection and if you like that, then get 4
"Behold my friends, a spoon. The most powerful weapon in existence."
the fact that it's easily attainable for 10 bucks makes it instantly worth it. But you've only played MGS1 and it would be much better if you played 2 and 3, and lucky for you 2 and 3 are coming in an HD collection being released this year. I'd recomend just getting that first and then after you blow through that getting 4.
