Too late for a great game
This game was excellent. It took many of the Doom great features and used them to give a step further in gaming.
Now is when you can say "At least a FPS with a plot!!".
It wasn't just shooting everything that move. Even more, if you do it, you will get frustrated soon. Sometimes you'll have to talk with characters. Sometimes you will find allies or friends.
And, in a certain part of the story, you will have to choose to fight in one side or another.
What else could you ask?
First of all, the graphics weren't too innovative by the time it was released.
Second, and most important... IT CAME TOO LATE!!
Why?? When people were moving towards new game technologies, like Quake and other polygon based engines, Strife went into the light, using a technology from two years before.
It was a pity, because the game couldn't enjoy the recognition that it deserved.
The Bottom Line
Late delivering for a very good game.
