Well... I've just start to listen the #28 in my car this morning (well, too much stuff to follow on radio since two weeks..Charlie hebdo.... terrorism in Belgium, France ... strange world!
)
Anyway, happy to hear you mention Geometry Wars 2 on PS3... one of my favorite games on that system (I'm now playing GW 3 on PS4).
If you really like Geometry wars, give a try to Gravity Crash on PS3... a mix between Asteroids & Lunar Lander, in a pure vector style.
