Does the maximum number of players increase with expansions?

[LeiraHoward]

After reading the FAQ, I tried searching the forums for this, but could not find an answer. I'm SURE it has to have been answered before, but I can't find it. (Sorry!)

My question: "Does the maximum number of players increase with expansions?"

The original Munchkin game states that it is for up to 6 players. However, once you add a few expansion packs, does the maximum increase? I would think that when you have added more classes and races and cards that you could fit a few more players. Is there official answer/guide to determine the proper number of players for the number of expansions you have? Or is it still 6 players maximum?

Thank you for your help!
