I am a big fan (played that game over and over and over in 1994-1995) of X-Com: UFO Defense/UFO: Enemy Unknown game, but still very excited to play this game.
Yes, I know, majority of gamers threat this game as "EVIL INCERNATE!" and the new XCOM: Enemy Unkown as "The Chosen One", but I don't agree on this ideology.
New XCOM: Enemy Unkown was not "that" great. It was a good game, yes, but had many many many flawes on gameplay. Developers of the game, and XCOM official forum community were obsessed on "how cool the hardness of the game", but neglect other areas and shortcomings. UFO: Aftermath/Aftershock/Afterlight series was interesting sequel towards UFO: Enemy Unkown game, but sadly they are not that popular especially because they are not AAA games. XCOM: Enemy Unkown had cool graphics, but couldn't benefit from the advantages and good parts of "UFO Trilogy")
I am more interested on this XCOM Tactical Shooter. The game is still not available, however continuously Evolving more and more. OK I admit, I also bored from current FPS frenzy, there are tons of boring copy-paste FPS games. However, If they can do what they promised, this game can be a classic (IF they can).
Footages of this game reminds me my days of System Shock, Thief and Undying.
System Shock 1-2 was a PC classic, but sadly new Bioshock games (alleged "spiritual successor), continously lessening the atmosphere/story and increasing the hack/slash routine. Yes yes, I know Bioshock Infinite become the crazed mega hit of this year. But it is still weak compared to System Shock 1-2, and just another console shooter.
This game can close that gap (again, IF they can), this game promises mystery, adventure, thrill, investigation and exploration. If they do it right, and not turn it another cliche console shooter, this game will have the atmosphere of System Shock, Thief and Undying games.
