I LOVE Miniature Golf, and Silver Putt uses a basic Miniature Golf for the design, and NAILS IT. You can create your own miniature golf course, the editor is a little clunky, but not too bad, and I sure as heck couldn’t do better. I come away from this game with a feeling that I would like to spend more time with it, so it gets points for addiction. The play is great: IF YOU LIKE MINIATURE GOLF.
One of the great things is that the game allows you to share game designs, which makes the whole thing a social event!
With respect to addictive properties, this game is a plus, if you are designing games, I would really make it be like golf.
As to play, well if you aren’t into miniature golf, there could be a negative, if you like miniature golf, then this is the game for you.
