I avoid mentioning some games because I am scared that people will try them. Can we just forget that Horizons exists, or that lawyer from Florida who shall not be named? If the game is irredeemable dreck, there is no point in discussing its problems.
At my book blog, I note that I give some of the longest, harshest reviews to books that get the next-to-best rating. When you really enjoy something, it is infuriating that there are just a few problems that keep joy from being perfected. Just fix these few things, and I can abandon all else to exult in your creation. The sheer excellence of the surrounding material is what makes the problems stand out so much.
Our complaints about games are usually signs that we like those games. Bugs, queues, and crashes are upsetting because they stand between us and the fun that we know to lie just beyond them. The details bug us because they distort what is otherwise a great design. The pettiness of the problem even makes it worse, since you can see how little it would take to fix it; you must be patient with big projects, but can someone take the five minutes to clear up this one annoying thing that is driving me insane?
