Why pre-order? Discount, additional content, early delivery. Do these really outweigh the possible disadvantages...don't think so.
Though there are dozens of games that I have thought of pre-ordering, I never have. I got taken on an order for commercial software in the mid-80s - bankruptcy meant I was out in the cold. I promised myself never to think of buying anything which was not being regularly delivered on a broad scale and finding good acceptance with few problems. That has helped me skip such winners as Windows ME and Vista and dozens of poorly rated, buggy, under-patched games and a bunch of games with draconian (and insufferable) DRM (this means you, EA, insert 'bronx cheer' noise effect here).
Unlike my son who felt an early investment in Age Of Empires II HD was important to maintain connected with his MMOG tribe, I stick with single-player and am very happy with the dozens of fine games - some dating back more than 10 years (Elder Scrolls, Dragon Age, Fallout, Jagged Alliance, Half Life, Deus EX, Thief, System Shock, etc).
ps I hereby place the idea of inline noise effects in the public domain..and if any one tries to patent the idea, I will hound you with friends at FSF.
