Lets make it clear first, is that real excitement or something that we usually call by greed but we do not realize it? LOL
Some time we cant differentiate it when we are dealing with gambling, we feel that we are excited but in fact it is just our greed when we want more while winning or when we want to recover after losses.
I will prefer to say that excitement is more about when I can enjoy the fun while playing the game without worrying about losing and winning.
