What small little thing makes you go "Instant no buy for me" in an upcoming game?

[IcaroRibeiro]

Motion controls, or anything that needs any movement outside of my fingers
First person shooters
Sport games

Outside of that, I think I can like anything

However right now exchange rates are terrible, games are soon going to be sold for 400 BRL, so I'm avoiding short games for full price unless they have really great replay vale (which for me means good customization or branching paths)
