Well, I know what they are, but I still have a few questions:

 

1. Are they free?

 

2. How big are they, on average? (compressed/zipped)

 

3. Can you still run the original version of the game?

 

4. Do they have online capabilities?

 

5. Do some games not allow total conversions?

 

6. Can you have more than one TC in your game?

 

 

Any other questions are welcome, thanks.

1. If you charge for a mod, it's illegal

 

2.  hundreds and hundreds of Megs

 

3.  On EAW, yes.  On others, it depends on how they manage mods.

 

4.  Again, in EAW, yes....I think

 

5.  Not that I know of, but there's probably at least one.

 

6.  It depends on what files they use, and how dedicated you are.  If you mean running at the same time, you just have to splice them to together, but that's hard and very detailed.  If you mean installed, it really runs down to the modability of the game.
