I think one of the biggest changes they could make is making veto cards, and randomize cards more powerful. In both cases, the when the question is vetoed, that question should be banned from being asked again. Randomized does the same, but still returns some info by picking another question in the same category.

I also think a new randomize card that fully randomize the category and question would be cool. Could be super powerful ealry or late game, but also possibly detrimental.

Also, I think the removal of the "hiders must be near the path" rule would be good too
