Basically, throughout each gen or year, exlplain how your fanboyism/non-fanboyism changed/didn't change and what you said. I will start off with an example.

2008 - Mario is famous, but Sonic is POPULAR (I was like 7)

2013 - Nintendo doesn't rehash their games like Call of Duty and they have quality over quantity, so they take time to polish their games so they will be masterpieces. What? You don't like the Wii U? All you care about is graphics. You don't care about the gameplay which a game needs because it is a game not a movie. You just play shooting games and don't want to enjoy the quality, polish, and originality with Nintendo games. Now I will go and fap to sexual Nintendo fan art. 

Early-Mid 2014 - I am very open-minded. It doesn't matter what device it is on, as long as the game is good, I will want to play it. Now I will go and fap to sexual Nintendo fan art.

Late 2014-Early 2015 - I don't care about video games. Now I will go and fap to other stuff.

Now - I kinda care about video games. But only gibberish can convey how I feel.

Edit: The title of this thread has the word "Evolution" and I saw an add here saying "Toothpaste has EVOLVED"! Coincidence? Muahaha

2006 - the Wii is literally the best purchase of my life!

2008 - I would sacrifice my family if it means sony winning the console warz

2013 - PS4 will cure cancer

2015 - eh PC is actually one of the best places to game now too bad the entire PC community has a stick up their ass

Wii Master Race to PlayStation Master Race to PC Master Race. Together it makes the Wii Wii PP CS34 Master Race!

2001 - playstation is better than nintendo

2006 - okay consoles lack RTS games

2009 - i built my own next gen console

2010 - PC masterrace

2013 - PC has no Tekken

2014 - Consoles are awesome, how i missed them

2015 - PS4 is the best console right now

I wish I weren't on my phone. I want to write an epic post. Basically everything I praise the Xbox 360 for doing last gen, I dismiss now because Sony is doing it.

1989-1990 (4-5 years old) - Everything is a Nintendo.

1991 (6 years old) - Nintendo is the best.

1994 (9 years old) - Sega is the best.

1996-1997 (11 and 12 years old)- Nintendo and Sega are the best. Sony is a fraud who sells mediocre games by using fancy commercials.

2000 (15 years old) - I'm old enough to get a job and make my own money. I don't have to choose one game system over another. I can support all of them. Fanboys are insecure losers.

oh easy

2005- I had a gamecube and that was awesome (6y old)
2008-At this point I had a PS2, DS, Gameboy and a PSP so the concept of fanboy didn't really exist for me (9y old)
2010-I bought a Wii and got buyers Wiimorse instantly-I still thought Nintendo was amazing (11y old)
2012- Bought a Wii U for Zelda and entered this very Nintendo centric comunity so I wouldn't feel bad about my purchase (13y old)
2013-I was a fanboy
2014-I grew up and stopped being a huge baby, bought a Vita and started looking at the other consoles, that Nintendo centric comunity now is unbearable at times.(15y old)
2015-Buying a PS4 later this year, and after that turd of an E3(and Nintendo just saying "fuck the Wii U") I'm not really feeling happy with the big N. (16y old)

There's a huge gap in your timeline buddy... like d2llewis I'm almost inspired to write a wall of text pointing out the hypocrisies of each and every fanbase.

Oh god i refuse to be called that. I commend PC as a great platform for some but when it comes down to it I need to sit on a sofa with a controller :P
