For ROTR I don't really remember as I rarely played it back then.
But I do fondly remember my first online match of Shockwave as well as some amusing moments. I recall my first being on that Armoured Fury map (it was a 3v3) and I was Fai, I recall taking a liking to that Road Grinder APC and more especially, those Officer units, which I made dozens of. I recall Hinata and Alias being present, in fact most of the matches I played involved them.
Some more moments that might amuse you:
-The old Railgun projectile being able to follow any air unit across the map without it actually hitting, produced a rather splendid sight
-Tank bunkers could almost take on any vehicle. The most fun combinations were Hammer Cannons and Adv ECMs
-Chinese missile subs operating on land
-Aurora Humvees
-Vehicles garrisoning train carts and utilising the fireports (Topols and Scuds produced hilarious results
)
-Losing half of your own base or units because I wasn't sure what that plasma ball of destruction was at first...or how it appeared
-Launching a Nuclear Missile on my own base to stop a single Lotus from capturing my base
-A bomb truck disguising as some building
-Phoenixes and Nuke MiGs failing us an AoD by blasting a super powered unit all the way to the end
-And some more that I can't quite remember
