Because cars are *never* recalled to fix bugs. I guess my wife has been a beta tester for her Sienna over the last decade, since it was just recalled because the spare tire can fall off in the middle of the road. I'd better tell her she should be furious.
You don't seem to understand the difference between a beta product and a finished product. Finished products still have bugs, you know, but the amount and the general quality level is a lot different. The level of problems in Civ 5 is well-beyond what you'd expect from a finished product (and I am sure the weren't a whole list of issues with your wife's Sienna that she was able to list after only owning it for a few weeks -- and if it did, you would be rightly furious over it).
