Got in exited that I could swing in the city as Spiderman.
Started playing and thought I was having a good time until the game started to show it's true colors.

Controls are aweful, the city is made out of cardboard box and it's immersion breaking.
I know it's free, but I think it's not worth it even that way.

From day 1, I get the "There was an issue with the server. Please restart your game" error followed by the game closing every 20 minutes of being in the game, be it menus, Towers, Story, Online, Krypt, etc. Didn't get a solution still, and it's pretty much unplayable like this.
Sometimes I'm doing a tower and the game decides to quit, so I lose all progress. Others I'm in the story, so I have to get in the game again and view de custscenes again if I didn't finish one.

Cannot recommend getting it for PC at the moment.
We are waiting now for a patch that'll come today or tomorrow, but they did not mention this issue, so my expectations are low.

The game is enjoyable, I like MK and this is no exception, when I can play it it's good, but I can for only 20 minutes every time, so it's not worth it.

Edit: Forgot to mention all the other problems such as graphical issues, being patches behind the consoles, and others that I cannot even complain because of my previous mentioned one.
