When you get comments that your game is a sandbox game. One might wonder if this is a good sign or bad.
For one, I think it is awesome that a game is considered to be a sandbox. It means that there is a lot of freedom for players to play with. A hidden goal of mine, 'yaaay!'.
On the other hand. These kind of games might never end. Especially when players are free to move in contrary to Monopoly. A game duration can become insanely long for such sandbox behavior.
Or is the whole sandbox principle just a misunderstanding, regarding the fact that it is an "open" wargame?
Is the direction good or bad?
What does it mean to the player base?
Xia is a rather popular space game that is very much a sandbox.
You just have to make sure your scoring system is balanced and you need specific end game conditions. The first to 20 points, for example.

It's difficult enough to create a balanced and fun game with only one objective.
I never had the intention to create a sandbox styled game. It simply started with designing a game. And by time, it grew to a bigger game by choices on before hand. The game itself kept the same size. Every part got tested (and scrapped if not right). Right now, I am finishing up a "new" last part. But more to that in another, yet to make, topic. Since it is finally time to finish things mechanical speaking.
So yes, it's cool to give the player a bunch of options, but you're only creating way more work for yourself. So consider feature creep when designing your game.
