My group had left over character points after making their characters. Can these be used for something? I couldn't find it in the rulebook.

nope...it says that any left over points are wasted...so use 'em. Can't remember the exact page but its in there

Yep, pretty much. Unless they maxed out points on table 3-2 already (short changing their stats), that's where you can put any 1's or 2's that are left over.

Its listed as no....

But as already stated stats are a god way to use up remaining points...
