I normally don't pre-order games because I honestly find it kind of silly and most of the time I'd rather wait until a price drop. But I went ahead and pre-ordered several games anyway:
Super Smash Bros. for 3DS and Wii U
Hyrule Warriors
Sherlock Holmes: Crimes and Punishments (I'm a Sherlock nerd...)
The Evil Within
Was thinking about Alien: Isolation as well but I should probably wait to find out if it'll actually even be good, considering the last Aliens game.
