I rather enjoyed them, and I still have them. I never completed #2 though, I think I'm stuck somewhere... a desert or something. The first one was fun, but I thought it almost impossible to beat the octopus thing (a Kraken?), it's the third boss in the first one, I think.
There was meant to be a 3rd on GameCube, kinda like FSA, being 2D with awesome effects in 3D. But I think it's been cancelled
.
So, I rated "awesome", in any case.
