I really enjoyed the Legacy Challenge for TS2, even though it did get awfully convoluted and silly. But the new version is really... boring. I know the goal was to simplify the challenge, but... really, where is the fun supposed to be? I think for myself I'm going to adapt the TS2 scoring system, because for TS3 there's nothing that really differs between the 'challenge' gameplay and normal gameplay, other than painting a ridiculous number of portraits.
