[Rainbow Yoshi]

1) Journey: This may be a short game but it doesn't undermine the fact that vast amounts of imagination have gone into making this game a classic. Truly the greatest impact I've had from a game
2) Metroid Prime: Retro studios pulled off a great feat with this game. Not only is visually fantastic today (excluding Samus Aran's features, they were in fact poor) but the exploration and combat system would still hold a mark today.
3) Uncharted 2: Among Thieves: This made a very big impact on me throughout gameplay as I did not expect as much as I got. The campaign was longer than anticipated, the storyline was very compelling, and the environments were breathtaking. Not only that but there was a multiplayer as well.
4) Uncharted 3: Drake's Deception: This was a very enjoyable game but couldn't quite live up to the expectations of it's predecessor. The storyline was still compelling and the environments were breathtaking but that great magic from impact was missing. The multiplayer has mainly improved over it's predecessor with some very intriguing maps heading it's way. Uncharted 3: Drake's Deception does however feature my favourite part in the franchise, which is the Dockyard and Cruise-Ship sections of the game.
5) Super Mario Galaxy 2: The predecessor to this game left a high amount of milestones to beat and Super Mario Galaxy 2 achieved those. The galaxies were very varied, the power-ups added to overall enjoyment, the boss battles never failed to impress and top it all off Yoshi was an integral part of the game.
