Eh, I got it before you deleted it. -- Why do you hesitate to talk? This competition is over, our discussion should not bother anyone any more. And that's why we're here, to talk, that's the purpose of this forum, so speak your mind, my friend.
Choosing a game you know very well will get you an advantage over someone who's hasn't played it before. True or false?
You wish! Persistence and motivation is what really matters. -- If you submitted your score early someone amazing, like me, could have beaten it with enough time and motivation given, and that would make the whole competition much more interesting, wouldn't it? But how can that happen if people "participate" without competing, that does not even make any sense.
Besides, you do not know what games other people have played before, which makes it all that much more interesting, a bit of gamble, and there might be cool strategies developed if everyone tried for the longest streak. In how many games can you really be better than everyone else? How well can you choose your "next game"? Would not that be interesting to find out?
Alternatively, why bother reporting scores, or even play, let us all just be friends and agree everyone is a winner?
