though races?
 

is there a list of the more challenging races to play against? (standard or mod's)
I just saw a list with a lot of new races and i don't know anymore which races to pick

Re: though races?
 

I have 3 answers for you;

1 - TDM modpack has tougher AI opponents. (My own BOD Mod will also, once it finishes it's beta stages)

2 - Many custom races out there, in fact most, will give you a greater challenge than the standard races.

3 - The more races in your race folder, the less often you get the same races in a game. This gives more time to learn what races do what, and, since you don't know what race you will be up against in any given game, makes the game more interesting from the get go.
