Nope, Globals got the short end on this update as well.
Before update they would be attacked by CWAs with 5 planes.
Now they will be attacked by AAs with 7-8 planes, and no buffs were given to air defense and SAMs of Global age. It's about the same situation if not worse.
As for benefits in MP, Space Age won't be enjoying much compared to CWA at the moment. 3 air unit upgrades, 5% boost in stats for each, and a 5% boost for basically every troop upgrade. Offensive silo is mostly reported as a hindrance (annoying scanning animation that you have to wait to finish before you can skip to next base in MP, 1000 oil cost and random target not that helpful). A choice of wonder, some economical (meh), one clear choice for wars, and 2 other what look to be meh wonders as well. Really, on the offense side, CWA vs SA in MP will be a barely noticeable difference, at least before the second part of SA is released.
