As someone who can spend hours looking at reviews, videos and interpreting smoke signals before taking the plunge on a new game, pre-orders don't seem like the best idea. Mainly because they're usually a terrible idea - as anyone who bought X: Rebirth in advance will probably tell you. Pre-ordering on Steam is an even less tempting proposition, thanks to Valve's great money-rake grabbing your hard-earned cash the very moment you click 'confirm'. According to users on the Steam forums , however, you can now cancel pre-orders without having to open a support ticket - just so long as the game hasn't been released yet.
Previously, if you'd changed your mind about a game you'd pre-ordered you had to contact Valve and hope they'd refund you the wonga (for our American readers, 'wonga' is a word which here means 'simoleons'). Now, as the image below shows, you can initiate this process yourself with the newly added, and seemingly automated, 'Refund an item' link. It's not clear yet whether you'll be refunded in Steam wallet credit or whether the money will go back to your card - so if you're on the fence about a game, it's still best to wait until impressions hit, no matter how tempting the digital pre-order tat is.
