(One thing I would like to preface before anyone reads this is there is a reason I don't typically respond to things, and that's my rambling (see, I'm already doing it), laying out my set-by-step process (if applicable, which it is here), and accidentally offending people, so be wary. Skip to the sixth paragraph (fuck me, I really need to learn how to condense my thoughts) to hear my opinion and skip my nonsense. And I apologize in advance for any offence, annoyance, and/or falling over dead from excessive explanations)
Now, I usually don't really respond to anything, I just read/watch something, gather my own opinions and move on. But in reading the responses I saw that there was a fairly small amount of people who have actually played, or had even seen the game. I just want there to be another opinion from someone who has actually played it. (That's not to say that the opinions of those who haven't played it don't matter, of course they do, I just prefer informed observations)
After reading Tom's post, then the responses, I went to see what was causing all the trouble. After a quick Google search, I found it and played through it.
A description of the game that's probably too long: You play as a tall, slender, black smudge walking around slowly, shooting the children and teachers (also silhouetted), leaving as little living as possible. The children will run, hide, play dead (some quivering), and even stand/sit paralyzed with fear. After 12 minutes or so the cops will come and and you will be forced to kill yourself (or you can kill yourself early if you so desire). There are also three different game modes: Historical, Gun Control, and Eagle Tears (unlocked in that order). You unlock each one by finishing the game (killing yourself) in each one. Historical I would hope is self-explanatory, in Gun Control you wield a Katana and slice-and-dice you victims, and finally, in Eagle Tears the teachers will all wield handguns and either try to kill you or kill the students themselves, in what I'm guessing, an attempt to side with you so you don't kill them (that is only speculation as I killed them before they were able to continue).
Now I have a fairly sadistic sense of humor and I have no personal connections with anyone involved in the incident, so I was able to play through this all three times without getting too terribly offended. Artistically the game is amazing, there is no question about that. And it's well made, and there are no signs of poor craftsmanship.
The message that this game portrays is one that I think only Tom and a few others (I only skimmed the comments following the third page, as they seemed to devolve into petty arguments about ad revenue) actually touched base on: gun control. The author of the game is 100% for gun control. On the credits & info screen, right in the center, he has a "Play Message From Creator" button. This plays an audio file of him expressing his motivation and reasons for making this game. He also goes on to talk about his stance on gun control laws. He makes it very clear that he is completely against liberation of guns. He even points out links he provided to "contact your state senator and representatives in congress", and the NRA gun legislation site. I don't know if this was ever brought up, by the ones who contacted Tom, or those of us who responded to this thread, but I do think it is important to recognize the creator's thoughts on his own game.
Now for my opinion (wow, didn't think I'd get this far). Tom, I think you did make the right choice. Hell, if I were in your shoes I would've done the exact same thing after the first e-mail. The one thing I would like clarified is how many actually listened to the creator's thought's and explanations. If everyone had heard it I think there is a very good chance that this game would still be online.
That is (finally) all.
