Hmm I have a few, I'm not usually vocal about these because each to their own, but I'll share for the topic.
1. I hate Street Fighter IV and all it's versions. I think it's flashy convoluted trash. I liked it at first and then woke up. I do, however, love Street Fighter II Champion Edition, Street Fighter Alpha 2, and Darkstalkers. The rest of the Capcom fighting stable? Fuck it.
2. Final Fantasy XIII is awesome, from my mouth, a fan of this series from the beginning. FFIV is still my fav all time game though. FFXIII-2 has a dumb story? Well so did FFX-2...and FFV...and FFVIII....and okay...even FFIV has some hokey bits and constant self sacrificies. Like I mentioned to my hipster cousin once in rebuttal: "When were these Shakespearean, high brow, intellectual efforts? I missed that period and I started with FF1. Whoosh."
3. I don't need a damn arcade stick to play a fighting game. When they started coming out on the SNES I was so happy to just finally use a pad to play them. I don't care about the claims from "the experts." I will concede that original 360 dpad is rubbish for them though.
4. The most recent Mortal Kombat is an awesome game. I hate the rest of the series minus the second. Street Fighter IV can once again kiss my ass.
5. The Atlus love. Hate it. Yeah they got a couple of games I like. I still think Working Designs (though gone) and Xseed are better.
6. Pokemon bores me aside from the first one I played (Red), and Diamond was pretty good. The rest? I just can't stick with it.
7. Every Zelda game since A Link to the Past, I compare them to it, and deem them lesser entities. Link's Awakening was a close shot though.
8. Super Mario World is the best Mario game ever. I think Mario 64 sucks, was ugly, and boring. If Mario 64 had been like Super Mario 3D Land, I would have been happy. I like 2D Mario best.
9. The competitive nature....people acting like how you play games, how good you are or are not at them, what games you play....like it's a measurement of yourself as a person or your self worth...I think that is some ludicrous garbage there. I hate how my chosen hobby of over 20 years has things like this infesting it. I mean, I'm pretty good at CoD, but some kid who kills me and talks shit, likely can't play some classic game, like say the original Mega Man or Contra, and beat it without dying like I can. Does it make either of us a better person? No....it's just a damn good hobby; stop poisoning it.
10. Super Smash Brothers is wonky, not fun, corny trash.
11. Code of Princess was funny but boring.
12. I think the Playstation Vita is the ultimate evolution of the handheld gaming console. I like the 3DS, sure, but the Vita is awesome. Drop that price shackle Sony and let this baby fly.
13. Sony needs to step into a phone booth, tear off it's suit, and walk out as 90's Sony.
14. I want Nintendo to embrace cutting edge specs again.
15. I like the Metal Gear games, but aside from MGS4 and PW, they all have crappy, obtuse controls. I also think the original overhead camera on MGS2 and 3 was trash...but it seemed to work okay for MGS1; maybe because the viewpoint was a bit higher or something, or the game was less complex.
Geez I'm gonna stop here, if I list everything I'll be typing all week.
