Activision/Infinity Ward i think i dont need to explain this. Sega ignoring fans and abandoning their own greatness, such disappoint EDIT: I'd actually like to mention Valve for being best company out there.
EA: Within the last seven or so years, EA has essentially killed gaming. Mass Effect 3 was an otherwise perfect game despite the backlash and laziness of Bioware during the very last sections of the story. Simcity was a total train-wreck on release day and it's only been just recently that EA has included an 'off-line' mode, after a year or so after the game was released. Any sport game that EA has released (Looking at you, FIFA) is filled with bugs and Battlefield 4 has honestly one of the worst campaigns I've ever seen alongside the diseased bugs that it tends to carry. Once upon a time, they used to be brilliant (For me, that was 2004) and they need to get their heads out of their *** and focus on professionalism in gaming and bring the magic back in their games like what they had in Burnout 3: Takedown or any NFS before Prostreet, not just broken games that are pumped out like a slaver run manufacturing plant every six months. Activision: To keep this short and simple, Activision needs to let COD die. Every single COD since Black Ops 1 has gotten worse and worse and are essentially milking the franchise for every single milky drop that they could. MW2 however is fantastic, and I still play it. Looking forward to Destiny however, hope it isn't corrupted like COD is. RARE (Under Microsoft): Just.....I cant. However, major kudos to Rockstar and Valve for essentially delivering masterpieces almost every single time. Bethesda also has my respect for Fallout 3 and Skyrim (Both of which I played forever.). Fallout 4, my love, you will be a reality one day...
Infinity Ward and Treyarch. All they do is make terrible CoD games. I would also say EA if it weren't for Madden and Battlefield.
