While I disagree with some of the creative choices (everything doesn't have to look just like Jedi Outcast..!), overall it's a pretty cool accomplishment, and I was excited to see some of my old faves like the Veamon and how they turned out in higher res.
I haven't tried the texture pack yet.
The coolest thing about these things is that they should be fully compatible online, even if people playing with you don't have them, since they're completely visual.
Sadly MotS doesn't have any unique model replacements, so some of the weapons look funny on the non-JK models. Still, pretty cool! I hope some other folks make new models for it, because the original creator is done working on it.
