For me a make-or-break factor would be the price tag. I didn't get CivBERT when it was released and it turned out like a good idea since it would have been a really bad mistake because I lost interest in it.
As in you never played RT? If that's the case, it's a shame because it made BE what it should have been in the first place. The game still has it's issues, but it was far more enjoyable than it was "vanilla". I enjoyed it for what it was, but I wasn't expecting SMAC II even though that would have been a great move on Firaxis' part.
As far as Civ 6 is concerned, as long as there is still Hotseat (a must have feature) I'll be picking it up. My wife and I play have been playing this series together for a long time, and it would be a shame not being able to do so with 6. Especially, since my wife was not a fan of Beyond Earth.
