If each game is resteemed by only 300 gamers, then its a few thousand unnecessary transactions. I am not worried about the Steem blockchain not absorbing this, just many individual feeds will get clogged.
And in addition I hardly resteem, because I want to keep an overview in my blog about what I have written. As you know there is still no filter possibility in steemit.com.
And these multiple repetitive resteems add no value.
