Let's get some random discussion going on...
Let's say within the next 50 years, holographic technology is perfected. Truly immersive gaming is now possible, FPS and RPG gamers rejoice. Think of your Call of Duty players, Skyrim, etc.
What happens to those humble RTS gamers (Age of Empires, Civilization, etc...) will they be forever relegated to using a clunky old monitor/keyboard/mouse?
If RTS games were to make it in a holographic format, what would even look like? God-mode style hovering over a battlefield, with floating controls? That'd certainly look nice, but you'd sacrifice the ability to micro in exchange for aesthetics, and I think that's something a lot of hardcore players wouldn't want.
