For me it would have to be the big three
MMO- Let's be honest here, MMOs aren't exactly doing so great right now. I've never been an MMO fan, I just could never get into them so when I hear the premise of a video game or see a teaser that looks totally awesome only to learn that it's going to be an MMO it sort of kills the excitement for me. It means a subscription model, it means sucky ass combat system and UI taking up 80% of the space. It means grinding the same dungeon over and over and doing every fetch quest possible.
Free to Play- Also known as Cash Grab 2000, While I'll admit some games do free to play well (Planetside 2) a lot of the times it's just filled with unbalanced mechanics and quite frankly the equipment and weapons are just never worth their price point.
Mobile- Honestly who gives a shit
Have you tried turn it off and on again?
QU:You look sad and frightened.
Stricken:i know this probably isn't the time or place now, but god damn millo is a hunk
