Game:Star Wars Jedi Knight (II): Jedi Outcast
Platform:PC

This is an absolutely magnificent game. For its time it had great graphics, the storyline is incredibly intricate, incredible voice acting and was one of the first games to have online multiplayer. Although when i first started playing this game i avoided the "Multiplayer" button i soon came to love the multiplayer, which included character customisation, lightsaber customisation and the ability to engage in "duels" with fellow competitors. Before i discovered this however the single player entertained me WELL after i had completed it, the amount of fun you can have from turning up the gore graphics, spawning a ton of rebel soldier with no guns and one very powerful dark jedi was incredible... HIGHLY recommend this game and its sequel "Jedi Knight: Jedi Academy" which FURTHER increased the customisation ability into single player too.

Game: The Legend Of Zelda: Twighlight Princess
Platform:Wii

Once again, this is another incredibly good game, despite it's lack of multiplayer. This was the first console game i ever owned, so you can see its significance to me, but this game is truly wonderous. Even though it is on the Nintendo Wii and therefore doesn't have as "crisp" graphics as the other two more powerful consoles, i still think this game looks beatiful, the art style compliments it perfectly. This game is completely open world, and as you progress through the game there are dungeon areas, with bosses at the end, each spectacular in their own ways. The use of the motion controls of the Wii doesn't feel taccy as it does in many other games, or as a last minute thought, but it feels absolutely perfect. The story is rich, engaging, and heartfelt, and i recommend this to ANY wii owner!

Game:Fallout 3 (+ DLC)
Platform:Xbox 360

Now i've seen a fair few people vote for this one, and for good reason. I'm genuinely struggling for words with this one because it is just THAT breathtaking, if you owned this game, you would never think a post-apocalyptic world be so beatiful, even the giant scorpians, ghouls and deathclaws (see pic) look ravishing, the story is engaging, more so because you literally are with your personalised character from birth. The gameplay is truly epic, even as you stride across the irradiated hills toward your next location there is ALWAYS something to catch your attention. The replayability of this game is simply staggering and i simply guarantee you that even with 600 replays of this game you will not find everything. Even with such a large game, what does Bethesda do? Bring out 5 pieces of Downloadable Content! Operation Anchorage is very militaristic and concentrates on a little less conversation and a little more on action (Elvis, woo). The Pitt is as dark and dank as it sounds, and yet still aesthetically pleasing and Broken Steel is an extention on the main story of Fallout and has some truly breathtaking spectacles.

And Xbox 360/PS3/PC owner MUST own this game.
