I just never see any real advantage to pre-ordering. The bonus items and such are rarely worthwhile, and there's always the possibility of bugs or server mishaps that'll make the game unplayable anyway. I've definitely become more of a "wait for a Steam Sale" kind of guy over the past couple of years.
Yeah, I'm totally with you Rorie, except in VERY specific circumstances. I mean, I knew I was going to buy and play BioShock: Infinite when it came out, so when Steam was running a deal where you could get the game at a discount plus XCOM: Enemy Unknown for free, it wasn't too difficult of a decision.
