How have games changed since the early developments?
In those days, a game was pretty straight forward with a single objective: Kill everything and get to the end alive. Today, there are many things you must do to the point some games are more stressful than enjoyable. You may have to follow a guy without being seen. Get to the communications station and broadcast a message, but oh no! You discover you need a part for the radio to work and you find yourself running around the map trying to complete your secondary objective in order to complete the primary objective and let's not forget that you can't set off alarms in the process of completing the mission.
You don't have to be a rocket scientist to see the graphics have evolved over the years becoming more and more realistic to the world that is familiar to us. As if the game itself wasn't expensive enough, now you need to invest a few hundred dollars into your PC to upgrade it and make the new releases enjoyable. *Cough cough* Assassin's Creed Unity *cough*.
What is the future of gaming?
We are already seeing gaming being transformed with Microsoft's new HoloLense technology. Basically, every anticipation you've had for virtural realtity is getting closer and closer to being in the palm of your hands very soon. This technology will do more than just let the user enjoy a game, of course, and it could change the way prototypes are built, business is conducted and so much more.
