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 have 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'll play. Maybe it's fun.
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 person who is willing to try activities he doesn't know or hasn't experienced before?
