Nope. This series' timeline is actually set in stone, there's no debate over it.

The hint was kinda cryptic huh? Well, the game I'm talking about actually involves a little bit of time travel.

Hint for #19:

Once upon a time, many fans of this series didn't want this developer to make this game. Now, years later, all fans want is for the developer to return to it.

Metroid Prime?

Nice job!

Agreed. It's not on my list this year, but I had it last year. That first level, in the bar, that's good fun! I actually think The Last of Us's gameplay mechanics, as far as the fluidity and versatility of the combat goes, were a definite step down from Uncharted 3. Drake just does everything you want the way you want him to. Can't wait for Uncharted 4 !

It's hard to compare, seeing as The Last of Us is about approaching your enemy with caution and quietly. One clear difference is how Joel and Drake incapacitate their foes from behind: Drake just quickly snaps the guy's neck and bam, he's dead. Joel has to take his time, because in real life, killing a person is not quick or easy. So I think it was made on purpose, so you can feel the struggle of hand-to-hand combat. U3 is more fluid of course... but it's possibly a case of apples and oranges.

Plus, TLoU puts a lot of emphasis on melee weapons (bats, axes, etc) rather than your bare hands. And yes, the first level on the bar was excellent

   Call of Duty & United Offensive Expansion

   System: PC
   Genre: First-Person Shooter
   Year: 2003, 2004
   Rank last year: 12 (v 7)

 Call of Duty is arguably one of the most influential first-person shooter games of all time and together with the United Offensive expansion pack, it also brings so much content that it keeps being replayable. The game also features the most addicting and competitive multiplayer-mode modelled after older 'arena-style' shooters like Quake and Unreal Tournament, but with a less 'jumpy', more realistic twist. It's so good, that this game remains one of the few games I ever play online and every once in a while, I'll even go back to it.

The single-player mode is where my real interest lies however. With both the main game and the expansion, Call of Duty covers most of the most iconic events in the European theatre of one the world's most influential periods in history; World War II. The action is epically presented in a very direct and sometimes shocking way and the horrors of this war are shown to the player from the perspective of three soldiers. One British, one American and one Russian. Each slowly moving towards the Reichstag in Berlin. The expansion adds to that another line of missions to play, with equal excitement.

Is this the Call of Duty game where the tutorial is played by the Russian, you throw potatoes instead of grenades and he yells at the nazis when using the fixed automatic gun remembering his dead family?

Game #18

This game's major feature, which also conveniently allowed the game to handle it's system's shortcomings, was proto-typed in another game that appeared earlier on the same system. There, it was used mainly in, but not exclusive to, one particular level.

Silent Hill?
