My top 3:
1) Metal Gear 2
2) Sonic Adventure 2
3) Beyond Good and Evil
Metal Gear 2, I was just completely blown away by. Of course, being the not-living-in-Japan kinda guy I am, I first played it back when MGS3: Subsistence was released. I played through MGS3 again, new camera was fun. Then I went through the original Metal Gear. It kinda sucked. Then Metal Gear 2. It was just AWESOME. The puzzles are awesome and clever. Especially the final boss. You've been stripped of all your weapons and you have to fight the most legendary soldier in all of ever. So what do you do? You run away like the scaredy cat you are, grab some hair spray and make a FLAMETHROWER. It's epic. And you can walk on acid as long as you're holding some chocolate. It makes so much sense that I love it. And you know those lame moral decision choices that are forced on you in so many other games? Well, Metal Gear 2 executes the system perfectly: if you punch a little kid, you lose HP! This game surely saved thousands of lives from child abuse.
Sonic Adventure 2. This is the best game ever made. No, really, the best. Except Metal Gear 2. But Metal Gear 2 cheated with the chocolate. Sonic Adventure 2 hbas something that I can't quite grasp, but it's just plain awesome. The story was amazing, something you'd never have expected from a Sonic game. It looks beautiful. I'd love it even if put to today's standards. And then it's just plain fun and awesome. And then the chao. I LOVE THE CHAO. I spent days and days of nonstop playing, trying to get those chao strong enough to win the karate tournament and save the orphanage! Oh, and did I mention Karate entirely consists of standing in place for a few seconds and slowly crawling over to your opponent and just blindly bopping them on the head? It's awesome like that and SA2 captured it beautifully.
Beyond Good and Evil was awesome. Seriously. Seriously, a combination of Metal Gear and Pokemon Snap? THAT'S THE BEST GAME EVER. Seriously. Pokemon Snap was the best game ever, and making a game combining it with Metal Gear is the best game ever, because Metal Gear 2 was the best game ever. Not to mention everybody is like an animal for some reason. That's like Sonic kinda. Sonic Adventure 2 was the best game ever. This is the best game ever. Except for Metal Gear 2. It cheated with fighting child abuse. Oh, and the story in Beyond Good and Evil pwned. CLIFFHANGER ENDING WHAT WHERE'S THAT DARNED SEQUEL oh wait there it is.
