Never played em.

From what I've heard, seen and read, they look fun. Just got a ps3 and after I beat Metal Gear, I'm thinking my next purchase is gonna be Tools of Destruction. I just got all of the ps2 Ratchet games for the absurdly low "buy it now" ebay price of $26.

So I'm gonna work my way through the series. Let me know what ya'll think of this stuff.

Very fun. Very underrrated. I just played Size Matters, which is a PSP port. I think a thread already exists for R&C. All the PS2 games are worth your puchase.

Up Your Arsenal was awesome. Size Matters is supposed to be the best one so far.

I personally prefer the Jak & Daxter series.

i've only really played the ps3 one... loved it

The one for PS3 was awesome. I loved every minute of it. It was also one of the best looking games I've ever played. An extension of the last game is coming to the PSN next week I believe. It's about 4 to 5 hours of gameplay for $14.99.

Size Matters was the worst one I've played by far.

I'd say:
Up Your Arsenol
Going Commando
Deadlocked
Size Matters

I never player the original or the PS3 one.

I've read that the ps2 port is kinda lame.
