It's cool of you to share those replays. It actually gave me a reason to check that feature out.
Though there are some problems with replays feature...
Rus crashed around the 18 minute mark. Tried 4 times to continue the replay beyond this but the game crashes each time.
Replays need better seeking abilities. Such as playing backwards, skipping to specific time points.
The replays have hiccups, i.e. an annihilator turret appeared to remain static (as though being upgraded) but was active as units magically died when near it.
Health is not being reported correctly and dead units, which grey out, continue to remain visible and continue firing for a period of time.
The play names are not recorded and displayed as Unknown.
An engineer was too far away from building it was constructing, its position was being displayed incorrectly.
