I just beat the final boss. Still have a ways to go.
It's certainly fun- I'm playing it far more than any other recent game- but I'm still a little disappointed. I recognize the achievement and all, but to me it still didn't match SM64 in any way. And don't get on my case about nostalgia and all that nonsense...I simply preferred almost everything about SM64 over Galaxy. I'm probably the odd duck in this situation, but I want my 3D Mario games to be just that; 3D. Galaxy felt much too linear. I like the sandbox design of SM64's levels above the two dimensional theme Galaxy took. I remember some people saying when Sunshine came out that they wished the entire game had been just the "secret" levels....well, your wish has been granted. But to me it's just not as fun.
AND YEAH, I just compared Sunshine to Galaxy. I recognize that pretty much every element of Galaxy is superior to Sunshine, and that the level design in the latter kinda sucked...but I think- and it pains me to say this- I had more fun in Sunshine than in Galaxy. So far, at least.
Also, since I'm venting, I have another complaint about the last two games: lack of real stars. Sure, there have been 120 stars since SM64, but it feels like (especially in Sunshine) that a lot of the stars are "bonus" stars. I want the stars to be part of the level. I recall in some Galaxy review (perhaps NWR, don't care to really look) that the author was amazed that entire galaxies were created just for one star. While any sane person would agree with that sentiment, *I* would rather see the standard 6 stars per level make a comeback as opposed to random levels thrown in there for funsies. I know I'm weird, but I would rather have cohesiveness over variety.
AND ANOTHER THING. I simply liked the way Mario controlled better in Sunshine as well. Galaxy was indeed closer to Mario's roots when it comes to acceleration (which sounds sort of petty now but, well, just think about it). Sunshine seemed faster and more responsive.
With all that said, however, it's a rare occasion that I binge on gaming the way I did (and am still doing) with SMG. It doesn't happen often that I lose track of time and stay up all night playing- I used to, but recently games just don't grab me that way. SMG did, and that's a big deal.
