Level 10?
 

I have a question about levels; if you buy any expansion packs do you go until level 15 or 20, instead of 10? Because it seems that you get really powerful and get to level 10 very quickly.
In case it helps the two expansion sets I got were: 1) The need for steed. And 2) De-ranged.

The expansions don't change the rules for the winning level.

I'll be honest, I've not tried to play with just those two expansions, so I'm not sure if one can become overpowered in that case. However, as said above, adding an expansion doesn't change the Winning Level. On the last page of the rules, there are suggestions for modifying play, but that ventures into complicated topics outside the Munchkin 101 charter.
