I, too, am an SC2 superfan. To me, SC2 hit the sweet spot in almost every way. Deviating from this point, I felt that
Elite was too technical for my tastes, and
Starflight was a bit boring and unforgiving.
That's just how they compare to SC2, in my opinion. Having said that, they're both excellent games. I still have a giant hand notated starmap from
Starflight stashed somewhere in my desk.
I'd recommend bumping them up over the other titles you mentioned.
Out of curiousity, are you using
The Ur-Quan Masters for your SC2 run these days? I think the team has done an excellent job, and I like being able to add in the 3DO media assets.
