YES! Hahaha, Finally making some good progress!
Okay, I have something for everyone who wants to try it:
A new version!
Don't worry, I made the wait worthwhile for everyone!
New stuff in this version:Lots!

1)
New Map, featuring the area of the Great Valley from the first LBT! The 2D map is thanks to Malte. I did the conversion from the 2D map to the 3D map used in the game.
2)
FIXED Collision problems as far as I can tell. I'd like playtesters to confirm this but I think I have the coding now so that the player is completely unable to walk through a wall.

I played around for a good 20 minutes without walking through one once.
3)
Improved the lighting on the map, creating natural shadows and a real light source from up in the sky.
4)
Improved Sky graphics! We now have a nice, pretty daytime sky with none of the ugly 'cube' effects from previous verions.
5)
Improved overall framerate and game performance with improved collision code and better map design.
6)
Put the START button on the HOST GAME screen in the proper place.

7)
Improved jumping. The cube no longer "skips" or "teleports" upward immediately after pressing the spacebar, but jumps smoothly as expected.

8)
Changed the game's font to one that isn't so ugly.

9)
Fixed a bunch of bugs from the previous version, as can be seen in the previous version's post.
10)
Options screen lets you change the resolution.KNOWN ISSUES (basically just cosmetic stuff and online issues at this point. The single player engine basically works.
):1) Camera collision still isn't very good. Left click isn't too bad. Right-click is pretty bad.

2) The chat text still doesn't stay properly in that chat box.
3) Online play has some framerate problems after about 10 minutes. I'm still looking into the cause of this. One of my friends here thinks it's a buffer overflow or something. I really have to do some research on this problem.
4) Littlefoot1616 was having trouble getting an earlier version (before the collision fixes and performance optimizations, etc.) of the program to load a map on his Vista machine.
5) If you change the resolution, the game crashes when you close it instead of closing properly.
6) Not enough features!
COMING SOON:1) Hopefully fix the issues above.

2) Water in the river bed on the map.
3) The creation of actual tasks to do in the game.

4) Changing sky graphics over time, including day/evening/sunset/night/sunrise cycles.

Now...finally..after no more delays...
The Land Before Time 3D RPG, V0.10If anyone finds any bugs other than camera collision issues or those mentioned directly here, please let me know! Thanks very much! B)
Also, if anyone could please tell me about how many Frames Per Second you're getting when running the game, that would be awesome too! I'm curious how the game runs on other systems.
TECHNICAL STUFF:You'll see some text in the top-left corner while you're playing the game.
"GRAVITY IS CURRENTLY APPLYING TO PLAYER" appears while the gravity function is working normally. Does not apply while a player is sliding down a hill, as a different set of functions handles that movement.
"FALL-THROUGH PROTECTION ON" appears when a function is in use that prevents the player from falling through a wall in situations where it could potentially happen otherwise. I wrote this one just today.

the number that appears there in that corner is the distance from half the height of the player above the player to the nearest object on the map below the player. It's just something I used for debugging purposes, don't worry about it.

The game broke 20MB in size today!
2526 lines of code.

:
Dual-cores not taken proper advantage of, and probably never will because I'm not that good of a programmer.
