I tried replaying it about 10 years ago but it’s got serious quality of life problems with the mission aspect of the game.
Particularly, it had no way to remember or save gear assignments between missions. So you would spend like 5 minutes at the start of every mission giving your guys the correct stuff for their stats. Every. Damn. Time.
The other thing that bugged me on missions was no keyboard shortcuts, particularly for moving the view up and down levels. You had to use the mouse to click a UI icon which was quite tedious.
Still fond memories, but a pity those aspects made it too tedious to replay for me.
The newer XCOM game fixed those aspects and allowed you to jump right into the action.
