X-Com has been adequately vindicated in my eyes. The Firaxis remake, while falling a small step short of my expectations, has again proven that the X-com game formula is positively luminous even after 18 years. I believe that Firaxis will make a sequel to it and the X-com series will continue for a while.
However, I really think this game could have potential based on what I've seen.
I hope that now that the Firaxis game is released and successful, they will feel free to take chances because they don't have to address the heavy "canon" of the original series.
What I think this game should be is a spin-off that shows a previous alien incursion having nothing to do with the rerelease or the originals except perhaps have a nod after the credits as to why the next force that opposes alien incursion is called X-com.
I want this game to be like Dark Souls meets Call of Cthulhu: Dark Corners of the Earth meets L.A. Noire, I want them to keep their promises and more that the player may need to get in their car and run away because all of a sudden something appears that's all together terrifying and begins eating whole houses and causing aneurysms in everybody that gets a good look at it. I want the agents to carry 1911s and shotguns but actually have no idea whether they will actually harm the things they are trying to investigate, at least not at first.
There should be times in this game where you are called into situations that are altogether inexplicably creepy, violent, intimidating and the only reasonable explanation is that it must somehow correlate to the alien invaders. There should be times, for instance, that you are called to investigate because somebody found their neighbor's door open in the middle of night, all their lights on, all of the plumbing in the house has vanished without a trace, the windows in the front of the house have somehow melted completely without damaging the frames and the entire family is missing except for a small pool of blood and a what "appears" to be part of a splintered femur that has penetrated eight inches into the engine block of the family car which is now standing straight up and partly fused into the concrete patio in back of the house, that's when you begin to hear the thumping.
That would be a game I would very much be interested in playing, one that represents the inexplicable terror of confrontation with alien beings that don't seem to follow any rules at all, physical or otherwise at least not at first. Eventually we may learn that there is an alien composed of microbes that accustically evaporates the metal in the plumbing and metabolizes it for energy but it travels using the sewer system and bounces off the walls with such force and with such a rate that you can hear it from 20 feet above ground, but the first time you encounter it you are overwhelmed by the unknown to such an extent that you feel you must evacuate or lose your agents. You should feel intense danger, it should feel like an extreme gamble when you see something you can't explain, because more often than not, it will kill you if you wait another 30 seconds.
