Sorry but I can't really accept 6 troops per mission, thats too small.
I think 8 would have been a better number.
Putting meat shields aside I prefered having option on how to deal with certain sits and having a bigger number of troops with different equipment was one of my favorite things about the old games.
I enjoyed games like
Commandos for what they were which was much more specific in how you played where as X-Com was more how you wanted to played, while yes it will probably still be that way but not as much as I would like.
