Nah, don't buy Morrowind for the Box, unless you just want to play it. Now, if you want to PLAY it, get either Morrowind plus all of the expansion packs or Morrowind Game of the Year to get all of the expansion packs for the PC. Now there is a fun game. The PC version allows you ro make mods for the game, including, but not limited to, new quests, NPCs, races, classes, spells, weapons, armor, and even whole new lands.
Here's my list:
Halo 1
Halo 2
Doom 3 (When it comes out)
Star Wars: Knights of the Old Republic
Star Wars: Knights of the Old Republic 2: The Sith Lords
Fable (It was short and easy, around 10 hours if you just ran through to the end, but VERY fun)
Morrowind Game of the Year Edition (This comes with two new main quests and two new islands)
Deus Ex: Invisible War (It's an RPG! No, its a FPS! No, its a stealth game! Actually, it's all that... and more!)
Thies: Deadly Shadows (If you like the Theif series or love stealth games)
The Chronicles of Riddick: Escape from Butcher Bay (Beautiful graphics... with much blood and gore)
Yeah, that's all I can think of right now... Oh, and a lil' game called...
Steel Battalion (Hey, it's a mech sim game that comes with a three-prong footpedal set and 40 button control bad with two joysticks! And it only costs $200!)
If you alreayd own SB...
Steel Battalion: Line of Contact (For $50, you can get the only multiplayer version of SB! Can only be played with the SB controller)
