It is not an authoritative statement but my opinion about the quality of the campaigns and tutorials that I have tried so far.
Yes, I made it to warn others, but nothing wrong with doing that in my opinion, as I wish someone warned me.
To get better you need in my opinion also criticism and not ignoring and denial of all obvious and big mistakes.
Just play it yourself and see.
and yeah, I might sound rude, but it is just the frustration talking out of me, no personal offense ment.
