It depends, I look at why it's poorly rated. If it's because of the graphics or the story, I look at the review, if it's because of the tags, I don't care.
On some games, I'm disappointed when we're presented with an MC who has to be the “evil” one (or when we can choose the path) but in the end throughout the story he wonders “was that the right choice to make?”
So I was wondering if you had any suggestions for good games with evil MCs...
