This definitely sounds like a Metal Gear Solid game. And the 'only game where you play as him' part probably means it's either Metal Gear Solid 2 or Metal Gear Rising: Revengeance. 

45 - Metroid: Zero Mission?

42 - Metroid: Samus Returns?

46: Mario Kart 8
44: Rock Band 3

Yup it's MGS2. Rising had already been guessed.

Turok: Evolution

Kingdom Two Crowns

These are all correct!

This is correct. Not the most well loved game admittedly, and despite its flaws, I've found myself coming back to it often over the years (for both single and multi player). With Nightdive remastering the first three, I'm hoping that Evolution and Rage Wars will also be on the way at some point.

Change YoY: -3   My Rating: 9.0 / 10

I never actually got around to playing the first two Suikoden games when they were first released back in the 90s, I honestly probably wasn't even aware they were a thing until much later in life. Over the years I heard a lot of people talk about them in reverence, as these masterpieces of their genre, with Suikoden II often singled out for particular praise. My chance to give them a try came when I noticed that they had both been released on the PS Store, so I decided to finally give the series a try. I certainly liked the first game well enough, but it was the second game in the series that truly stood out to me, as it had done to so many others before me.

There was simply something different about the story of the game, the heavy political overtones weaved in with the story of war and struggle against a superior opponent were quite unusual at the time, and in a lot of ways still are. Of course, that wouldn't matter without good writing, and Suikoden II has that as well, alongside a genuinely despicable villain, a great music score by Miki Higashino, and visuals that still hold up remarkably well thanks to the developers decision to use sprites rather than 3D models. It's an excellent game, and one of the finest examples of its genre both at the time and still today. I'm very much looking forward to the HD remasters, whenever they might be released.

44. Kirby Superstar Ultra
I had never played a Kirby game before picking this up, unless you count Kirby's Avalanche which was really just a re-skinned Puyo-puyo game. The easier games were fun distractions, good for relaxing with, while the harder ones gave a satisfying challenge. I spent most of my time in the Arena fighting enemies or 'Helper to Hero' which let you playa boss rush as any of the 20 'helper' characters. But the stand out game was Meta Knight's Revenge. The characters, level design, and music were all top notch and I loved the cameo from Dynablade.

Some more clues.

48 - Super Street Fighter II

- Whilst your journey through the game is mostly random, you’ll always end it by visiting the same three countries.
- The main reason you’re travelling to these countries is to give people a beat down.
- Some of the places you could find yourself having a fight include a dock, a beach, an air force base, and a factory.

47 - Sonic the Hedgehog (Master System)
- The first boss is comically easy if you play the handheld version of this game.

- There are two other games that share the same title as this, one of which was released in the same year on a more powerful system.

45 - Alundra
- The protagonist has to enter people’s dreams in order to progress through this adventure.
- The word ‘adventures’ was part of the title of this game in Europe. The NTSC version simply had the protagonist’s name as the title.
- An exclusive to one of Nintendo’s competitors, it took a lot of influence from the early Zelda titles of previous generations.

44
- You solve everyone’s problems but your own in less than a day. But what you do discover along the way does offer you hope in your search for an old friend.
