Let see if I've got this right....
TK admitted that there was an issue only when merging title 2 and title 3, stated that he'd fix it in the next patch (with the emphasis on HE, there is no team at ThirWire), and you're singling him out for poor QC? How long have you been simming/gaming?
Falcon 4.0 (large team effort); released in 1998, all but unplayable until the community stepped in.
MiG Alley (team effort); released 1999, buggy, took two patches to fix it, still buggy in multiplayer
LOMAC, (large team effort), memory leaks, etc. Wasn't really fixed until they released Flaming Cliffs.
Now, I'm not putting down the aforementioned sims, nor their developers. I've just used them as examples, to illustrate my point... And that is, that even a team of devs working with a generous budget, still won't guarantee that a sim (or an app, or even an operating system) will be totally free of bugs. Come to think of it, one has to look no further than Micro$oft
