My reasoning to block and ignore almost all Sandbox games is Story Fragmentation.
What do I mean by this?
Well, I prefer to read stories in a sequential form. Sandbox games, take all the pages of the book, throw them to the wind and tell you to go and find the pages that are spread everywhere, out of sequence, with no connection.
Why do they do it? To artificially extend play time. To force the absurdity of repeating the same action expecting different results. To turn the story into a puzzle that will never be complete because some pieces aren't in the game.
Instead of reading a pleasant story, after hours and hours of unsuccessfully combing through the navigation maps, looking for the crumbs of story here and there, you are, as the creators intended, frustrated and confused with no idea what the story even is or if you missed anything by doing things out of a hidden (on purpose) arbitrary order that you are never informed about.
That's when I delete the game files, the saves and ignore the game, also place the Dev on a list of distrusted creators.
If this is going to be a Sandbox game, I prefer to do it right now, and not even bother with what was a nice story.
Peace
