I was trashing some old stuff out of my drawer a few days back and stumble across my old kotor2 cds. Since it was a game that, unlike the first version of Kotor, I have sincerely disliked due to the various reasons everyone already knows about, I've played only a couple of times after I bought it and never touched again. I then remember having read something about a year or so of group of modders that where trying to add new stuff to the game in order to give at least a more dignifying ending to it and figured: "whatta heck, I think I might give kotor2 another shot to see how the modification turned out". Having started digging on the web for the mod I found the Team-Gizka website and imagine my surprise finding out that the mod is STILL being done, and with no estimate of when will be completed.
In my opinion, this signifies that the programmers must have gotten sick of messing with it for god knows how long and left at that. I mean, I've never heard of a particular mod for any game taking that long to be done, maybe because it's very easy to lose interest in modding if you stumble across a problem you can't solve for not having the appropriate tools to do it. Especially if it is something its being done on your free time and you are not being paid for it.
To conclude, I think team-gizka just got frustrated with kotor2 and decided to give it a rest. The mod may be completed at some point, but that may happen only when, or if, people become interested in starwars games again start fuzzling about it, like an announcement of a Kotor 3 or footage of another SW rpg.
