Seriously, what is going through your head when you click to invite friends? Does this actually work? Does anybody actually think oh, Dave invited me to play , I might actually give that a go? The only thing inviting me to play is likely to do is remove you from my friends list. If Im already playing the game and you are inviting me to do something on that particular game, then fine, thats acceptable; Im already playing the game out of choice and your invite is good for both parties, but if youre inviting me to start playing, the only thing youre achieving is giving me another pointless notification.
