From a DC reader of more than 20 years....
I just finished reading the Superman-Batman graphic novel "Supergirl" and I was ready for this.
Now, don't take me as a slouch when it comes to gaming. I can play, I can play madden, just beat Gears of War and have a damn good hockey game. Heck, after two years in Iraq with Gaming as one of the only safe outlets, I feel qualified to comment on this matter.
It is fun. If you read the comics, Superman is all about restraint. Except when it came to Doomsday, and if you don't know who this is, you shouldn't even be commenting on the game.
Yes Superman could just snap but snapping just enough to get it done in a way that cause the least amount of casualities that is where the game rings true. He even said himself that when he touches a human he has to concentrate to make sure he doesn't crush them because they are so fragile.
Recommended reading to understand:
"Death of Superman"
If you are like me and your wife says what are you doing when you are playing and reply, "Saving the world." And she understands, that is what it is all about.....
heck, i like flying the most. If it was me for real, I wouldn't even need powers, just let me fly!!!!!
