I'm not sure what my GOTY would be as there haven't been any games lately that I've really been enjoying. I was into Far Cry 3 but the gameplay got old pretty fast, though I still love it for the graphics. Minecraft has easily become one of my favorite games of all time, but now I'm waiting for updates on all the mods I use, so I haven't been playing it at all.
One game, however, that I recently found, has blown my mind completely. It's called Space Engine. I wouldn't even really say this is a game, but just an absolutely incredible simulation of outer space. You can literally go anywhere...in the entire universe. Yea, you can actually start at earth, and watch as you zoom out of the ENTIRE MILKY WAY GALAXY. You are going to have to increase your speed as you zoom, however, as the distance you will have to travel increases dramatically as you leave the solar system. I really can't believe I have never heard of this program until now. I could never truly appreciate the size of our galaxy until I started using this. It's unbelievable.
And if that isn't awesome enough, you can actually pick a random star, go to it, and there will be randomly generated planets around it that you can actually zoom all the way into. It is just an amazing program, and I highly recommend people check it out if you really love space. My only qualm with it is it is kind of glitchy sometimes when you try to zoom into planets, and if you move too fast through space it can lag and sometimes crash. But other than that, I have had no problems with it. It is the coolest program I have ever found
