Ok...so I installed them all and used the Grey Wolves expansion 3 for SH 3 and used TMO+RSDRC for SH 4. It interesting how the graphics for SH3 have aged since the last time I played but messing with the nVidia graphics controls helped quite a bit. I'm liking the feel of SH 3 but SH 4 also has advanteges especially in graphics. I'm not a fan of SH 5 yet...walking through the sub is cool but it seems a bit buggy or something.
Aces of the Deep...I remember playing that on my 486 with 4 mb RAM.

It was a fun game!
