As humorous as the chart is, I dispute that it's an actual representation of consensus in the fanbase. I realize that's a broad statement to make, but I don't think it actually holds water. Of all the games listed, the only one I've seen have any sort of re-evaluation was Halo 4. The rest are generally regarded the same way now as they were at launch.
I wasn't old enough to have been immersed in the discourse surrounding Halo 2 or 3, but I know for a fact that both were lambasted at launch, before eventually being warmed up to.
Hell, even in the Escapist's own words from 2007 "
Halo 2, in many ways, felt like a bastardization, a mutated genetic experiment performed upon the near perfect console shooter that was
Halo 1".
Do you remember the controversy about how little fighting you did on earth in Halo 2? The fact that you had to play as the arbiter? The cliffhanger? Now it is considered by many to be the best in the franchise.
Halo 3 had its map packs. ODST had its price. Don't even get me started on how people felt about Reach's story, and the armour abilities in multiplayer. All of these games were heavily criticised over their lifespans, before eventually being considered classics as time went on.
The game comes out, people gush about it for about a week, then the rose-tinted goggles wear off, and players start to think about the game more objectively, then apparently the Halo rage sets in, and the forums spend the next few years berating the game until the next one comes out, and people start to look back on the last game a little more fondly, as they are busy criticising the new game.
I
never thought this would happen to Halo 5, which according to the chart's pattern is in the "in retrospect, it isnt as bad as originally thought", but there are already more than enough threads in the Halo Reddit about how Halo 5's previously derided monetisation and progression systems were way better than Halo Infinite's current system.
All the Halo community knows is that the old ones are great, the last one was okay, but the new one is definitely the worst ever.
You are right about Halo 4, though. My opinion on that game seems to shift from "almost the best" to "almost the worst", and then back again, every time I replay it.
