(5)Metroid Prime vs (4)Half-Life 2 2015

Ulti's Analysis
Rematches are very rarely as good as the original, and it's very rare for the loser of the original to turn it around in a rematch. There's a reason it's such a big deal whenever a rematch reverses a result. There's a massive precedent for this stretching across many contests, but my favorite example is Sonic vs Samus in 2002 and 2003.

In 2002, Samus came back from down 1500 in the final 3 hours to beat Sonic by 34 votes, and when CJayC legitimized the result it set off one of the biggest firestorms in contest history. In 2004, CJayC had the idea to set up the bracket so that Sonic and Samus would have a big rematch.

There are other examples of rematches not being very good, like Snake having to beat Knuckles three years in a row, but you get the idea. Things like Crono turning around the Vincent upset a year later or Link getting revenge on Cloud don't happen very often.

So when Metroid Prime and Half-Life 2 were set up to have a rematch of their classic from Game of the Decade (http://www.gamefaqs.com/poll/4182-northeast-division-final-metroid-prime-vs-half-life-2), I knew how it was going to go. Add in Half-Life series fans becoming very disenfranchised by the lack of Half-Life 3 news, and you have a recipe for a virtual parallel to Sonic vs Samus from 2004.

Sure enough, the match was 60-40 right at the start and Metroid Prime never looked back. Given how similar the percentages here were to Skyrim vs Goldeneye, it led to the obvious question of Goldeneye vs Half-Life 2. I would assume Goldeneye is the stronger game for rather obvious reasons (NOT THE LEAST OF WHICH IS WHERE THE FUCK IS MY HALF-LIFE 3), but Metroid Prime would have a lot to say about that en route to yet another classic match for one Samus Aran.
