Sega. Great games like Valkyria Chronicles and Yakuza, poor marketing for anything that isn't Sonic or an American move tie-in. The same thing could be said for Namco and its treatment of Tales of Graces.

i don't have one favorite so i'll just list them all

SCEJ didn't make more games, and haven't made Legend of Dragoon or any RPGs yet, they're just sleeping under all the SCEA and SCEE crap that i barely care about, more originality and less fancy graphical shooters please.

Microsoft seem to have ignored their older IPs completely and are now just focusing on crap no one cares about

Nintendo always making gimmicks just to be "Different" but in reality most of the stuff doesn't work so well, and people just want their old , fun and engaging games back.

Valve stop emptying my wallet please.

Bethesda please don't go into the "Console X exclusive Add on content " Please, i wan't Skyrim on my PC like everyone else, don't make me wait a whole year just to play an Add on because Microsoft/Sony talked sexy with you.

Not alot really. A few irritations maybe but nothing Nintendo does really makes me angry. Quite the reverse really. I still advocate using Kirby's Epic Yarn for anger management. It soothes the pain.

Nintendo - Region Locking for 3DS and Wii

Damn straight, those are 2/3 of my biggest annoyances. My #1 however was....

WHERE WAS PIKMIN 3!?!?!?!?! YOU SAID WII GAME, NOT WII U, DON'T PORT IT YOU LOUSY PUNKS!!!!

Also to add to your point on no Wii games, no XenoBlade, The Last Story, or well anything. They even announced Mario Party 9, why not show it? Also no DS games, even though there is a Kirby coming out.

Nintendo, actually maybe NOA, why do you ignore titles such as xenoblade, TLS, pandora's tower, soma bringer???

Square Enix - sequal, prequal and spinoffs announced and being made out the wazoo but still no Final Fantasy XV. I can't fathom why.

18 years without a real Mario game.

Abysmal approach to the virtual console.

2 (soon 2.5) years and motion plus only has the game it launched with.

Zelda looks like it will be 'windwakered' in respect to controls given the direction Nintendo is going with Wii-U.

Zipper: SOCOM 4..... Really Zipper?

GG: Killzone 3: Love the game but missing some obvious feature (many in KZ2) that could make the game perfect

Sony: I'm not the greatest people person, but I'm sure there was an alternative to handling Geohot the way you did. This month-long outage really hurt SOCOM 4 (not that it would be super successful anyway) and slowed down KZ3's legs a bit (it began to drop 10k each weak of the outage I think.

Team ICO: HURRY UP!

Insomniac: I'm not sure about this new Ratchet & Clank

Hitman devs: They said they were making the game more accessible.... This angers me

I know you said favorite company, but I took this thread as an oppurtunity to express all of my disdain towards every dev/company I like.

I'll do all 3
Nintendo: like some said even with their numbers I still think the Wii was a trend like iPhone is for phones.... with legs for sure.... but how many gamers bought a Wii and got another system later.... or how many casual got a Wii a couple games and since then it's taking dust.... or even if it's not they are still not buying new games (cause they are casual and don't know you can actually have a sequel to a game :P) so yeah WiiU will need some heavy marketing to attract the casual and get them to buy the new system.... so either they'll bomb or once again they'll have great sales on system.... but not so great attached rate.... bottom line if they making money all is well....
but still I'd like to see them step up and give us the 21st century super nes equivalent....

Sony: well they actually went up in my book.... people are complaining about their marketing.... I'm not saying I like it but at least they stoped doing tacky non in game footage and promoting extravagant things out of their asses.... they are way more in phase with their product... and they finally produce great titles in quantity asnd like you said should probably push them a bit more than they do.... go figure when they have nothing to talk about they over do it... and when they have they down play it..... oh well anyway I think it's too little too late anyway..... but on the other hand I think they'll learn from their mistakes and next gen is going to be great for them

MS: now I'm pissed off that they don't define their strategy more clearly in the entire entertainement division.... they did a great job till this year..... then again even though they have rumors leaking all the time.... they are pretty good at keeping the good stuff hidden.... I have no doubt that they'll end up doing the right thing at the right time.... because that's what MS does.... I think their next gen will be the most impressive.... in that they'll really differenciate themselves from the regular consol market..... but still as a gamer I'm scared of what they are going to do from now till then and after.... wait and see....
