A: Hey, do you like to do bungee jumping?
B: Um, OK. Haven't done it before, but let's try it.
I'm not looking for adventurous or something similar. That word should also fit in less action-packed activities:
A: I've a new board game. Do you like to play?
B: I don't know this game and, actually, I don't like these varieties of games but I will do. Maybe it is funny.
First I thought about open-minded but I think this means more willing to listen to people, think about their ideas, arguments, ... and accept them (not necessarily agree).
What word describes a person who is willing to try activities he don't know or hasn't experienced before?
