Used to love Ubisoft, especially because of Splinter Cell and Prince of Persia.
Splinter Cell Double Agent was mediocre, and Conviction/Blacklist are just totally different games with a brand name slapped onto it. It's also disgusting how they've handled the character of Sam Fisher and how violent they've made him.
Prince of Persia doesn't interest me anymore.
I don't really have a favorite console developer. I guess it'll be Naughty Dog, since DICE has completely fucked up the Battlefield series, whereas Naughty Dog seems at least open to the possibility of listening to criticism and changing.
