Forgive me if, because of bad memory, I've forgotten some that I would have included.
20/ BattleToads - NES
19/ Assassin's Creed - Xb360/PS3
18/ Call of Duty 4 - Xb360/PS3
17/ Legend of Zelda: Twilight Princess - Wii
16/ Metal Gear Solid 3: Snake Eater/Subsistance - PS2
15/ BioShock - Xb360
14/ Super Mario Bros. 3 - NES
13/ Super Mario World - SNES
12/ StarFox - N64
11/ Tony Hawk's Pro Skater 2 - PSX
10/ Shadows of the Colossus - PS2
9/ Grand Theft Auto III - PS2
8/ Legend of Zelda: Ocarina of Time - N64
7/ Metal Gear Solid 2: Sons of Liberty/Substance - PS2/Xbox
6/ Super Mario Bros. - NES
5/ GoldenEye - N64
Single player was fun. I enjoyed going through and shooting the goofy character models in a story based on the movie. Whatever. But I'll never forget the hours and hours of 4-player split-screen multiplayer. Hiding in the bathroom stalls and in that vent above. Planting trip mines on the walls of the narrow hallway where there's no escape. Everything about that game's multiplayer was perfect. The only games that have ever come close were Halo 2 and Call of Duty 4.
4/ Super Mario 64 - N64
I was so happy the day I got my N64. I had been asking for it for Christmas and my parents (or Santa) happened to get their hands on one and bought a copy of Super Mario 64 with it. This is the defining moment for 3D games. What more could you ask for? I collected every single star available in that game at least 3 times over and have since purchased it for old-time's sake on my Wii.
3/ Grand Theft Auto IV - Xb360/PS3
About a week ago I attained a 100% completion on this game. It is that good. The story is captivating. The characters are believable. The pains that your character goes through. It is all so well-done. And it is also one of the best looking games on the market. And than there's the multiplayer. Give up to 16 players free-roam of a giant New York-based map and see what happens. Perfect.
2/ Metal Gear Solid - PSX
I remember just renting this game on a whim. I had heard good things so I decided to check it out. I was only about 10 or 11 when it came out but the moment I started playing it I knew it was an incredible game. It looked INCREDIBLE (back then). It was unlike anything else I had ever played. And the boss battles!! I never thought that there could be a more enjoyable game until...
1/ Metal Gear Solid 4: Guns of the Patriots - PS3
This is the most enjoyable game I've ever played. I don't think I've spent more time just in awe of how wonderfully put together a videogame could be. The story is so perfect. Not only is it perfect but it answers every single question you've ever had about the series. Anyone remember Metal Gear Solid 2? Yea. It's not confusing anymore after this game. That's a big accomplishment. I haven't even begun to dive into the multiplayer but I'm sure that it is only an extra perk to be added to the list. I would definitely not recommend this game to anybody that hasn't played ANY of the other Metal Gear games though. If you have a 80GB, 60GB, or 20GB PS3, go pick up the Metal Gear Solid triple pack that was just released earlier this year and play Metal Gear Solid 3 THEN Metal Gear Solid THEN Metal Gear Solid 2. THEN play Metal Gear Solid 4. Just so you can play chronologically (story-wise). It is that good. I give it a 100 out of 10.
I hope you enjoyed Part 1 of my dedication to my nerdiness. Part 2 may be coming in the form of a FoxHound logo tattoo on my shoulder.
