Gas giants Good or Bad?

[Egregius]

I'm glad for the 'can only colonize home planet type' option, as taking over a neutral or just conquering a race with a different planet type gives you way too much advantage.

Anyway, if Gas giants are inhospitable because of the winds, the poles should be large enough and windless enough.

Actually there should be an option to make colonizing other types possible via research but not capturable.
