Henrym;
I played SC original and then shifted over to SCXIIc and I have never been sorry. I like you played 688i and still do, but I really like SCXIIc.
The only problem I have is when I went to XP I get the flashing, I had it in DW but they fixed that. It is an annoyance but I have just learned to ignore it.
SCXIIc is great, I have never played MP so I cannot comment. Well yes I can, I don't know how.
I am working on some SC mission now using SCXIIc and Subgroup will post them if they measure up. They will roughly be based on my experience in subs from 1962 to 1981, but I will blow things up because I like to. I like to sneak in and all but in the end I just got to kill something.
Try SCXIIc, you'll love it,
