"Another great game. Better than the slightly overrated Gunstar Heroes. *hides behind a wall*"
I thought so too. I got the Gunstar pack this summer at the behest of my friend because "Gunstar is awesome!," only to be totally smitten with Alien Soldier. Barely even played Gunstar (and didn't even touch Headdy,) go figure Too bad the scoring system is oddly BROKEN in the PS2 version, hopefully this isn't an issue in the VC release.
I played SMB3 on the All-Stars pack, after playing pretty much all of the SNES/N64 Mario games and some of the Game Boy ones. I was pretty... confused? I had some fun with it, but not as much as SMB or the Lost Levels. And speaking of weirdness, the game I enjoyed the most on the cart was the one that wasn't even a Mario game!
I really like Super Mario World, and I loved Mario 64 and Yoshi's Island. Yoshi's Island is just so offbeat and damn creative, it really caught me when I first played it and even now I still am amazed by some of the detail in the game. Of course I also favour Super Mario RPG, but I guess that doesn't count...
