I play it almost exclusively at the time, but you also have to invest a lot of time, but more on that later.
One can describe it as a coarse creative kit for adventure games. Of course, show a lot of games from the community, that everything can be implemented, and that the design and programming possibilities are almost unlimited. But precisely those adventure games will at least set the tone at the top.
I love it a lot of fun and I often start my Xbox One only reason. However, you have to invest a lot of time. Because a big but is the strong monetization of the title. This retail version has Spark Premium for one month. This is sorely needed. Because one wants to unlock new features or new props to call his own, you have to either jump the collected in-game currency or pay real money. Unfortunately, it appears that I can not buy anything with the game currency. Here's a recent example: I wanted the so-called "fighters package" buy three new game characters. My Spark Premium but has expired. Until now it was not possible for me to buy that pack only with the tedious collected ingame currency.
In addition, the prices are very high. One year Spark Premium costs 100 Euro, so therefore even more than Xbox Live - so the price is too high for the value would be worthwhile. The individual properties to buy with money is very expensive. Single packs can cost around 25 euros. All in all you can spend a lot of money if you want.
However: I would insist only because it really bothers me, because I otherwise the image and the community very much did. You spend many hours trying to experiment or collaborate on projects. If there's a will there, you can implement almost everything.
