Different engine and such. 1.0 used crystal tools, which was an in house engine from SE that was forced upon tanaka to use and it was not good for MMO. Great for single player games. While 1.0 was a beautiful beautiful game, at the time of release it took a power house of a pc to run. I think near the end of the its life span a good computer could run it while looking great. The game was really beautiful compared to what we have now, but it came with a performance cost.I am not sure a texture pack is something that is possible, but I miss the combat animations.
