I honestly am considering pirating the game just to see if I like it. If I do, then I would pay for it in a heartbeat.
There are extended walkthrough videos on sites like giantbomb.com, and it's not hard to read comments and reviews and see why some people love it and some people hate it. Gamers are different, you can put their likes and dislikes into categories that mirror your own.
There is no need to pirate the game, stop justifying. Watch some videos, read some impressions, make up your mind.
A quick summary from my point of view:
+ Great mouse aim, smooth shooting
+ Lovely art style, great visuals
+ Diablo as an FPS, never has a game been so easy to categorize
+ Addicting gun collection, new game+ mode and coop
- Clunky UI
- Have to force AA, larger FOV and some other niche PC gamer stuff
There, done. Watch a video, read that, then you should know if you want the game.
