Prime 2, Hunters, Federation Force and now Prime 4 are the only ones I've missed/skipped.

I actually played Prime 3 when it came out, might have even been my first game in the series. Can't remember if I got the VC release of Super before or after.

But I've heard good things about Echoes, also that its pretty tough. Going to play it on PrimeHack for mouse controls. Just recently played through Prime 1 that way and I actually enjoyed it a lot more than my first playthrough of the game and a lot of that had to do with the free aim (and drawing my own 2D map to mark places to come back to later. That helped a lot with backtracking and finding the artifacts.)
