Alpha Protocol has been receiving mixed reviews from game reviewers, mainly from mainstream game websites. However, I found them to be pretty biased overall. They criticize Alpha Protocol's aiming and shooting mechanics to be imprecise and too reliant on a dice roll. they even criticize it for being buggy and filled with glitches. However, they praise Fallout 3 like it was God's gift from Heaven (I'm only a fan of the first two Fallout games) when that game was extremely buggy and had random aiming shooting mechanics. It seems that game reviewers rely on polish instead of actual game design, not that polish isn't important but game design is what makes the game. They even give high scores to any AAA hyped game, which explains why they've overlooked the flaws of Modern Warfare 2.
I haven't played Alpha Protocol yet, but I'm sure it will be a pretty good game that isn't as flawed as critics make it out to be, I enjoyed Obsidians past games before too and they were buggy but well designed.
