I haven't played Fallout Tactics ever, but from what I've heard those who like it might take a look at Jagged Alliance (JA).
About Sacrifice : I liked that game, because it's so weird, but unfortunately NEVER managed to get a job done ! I tried I think 3 times the very first missions but never succeeded beyond mission 2 or 3 (apart from the Tutorial) ! <img src="/ubbthreads/images/graemlins/puppyeyes.gif" alt="" />
