Dang. I already have a bunch of those, but I guess I could give some as gifts.
It's probably worth it just for sonic and the allstars racing transformed, honestly. I was pleasantly surprised what a good racing game Sega made...
...then I did pretty much everything you can do in it in the 3 free weekends they've had for it.
I don't think the sonic adventure games have aged all that well. they're plagued by some really awful camera issues that only ever seemed bearable because I didn't know any better.
I don't remember the first one as well, but I definitely remember issues with the second. especially on treasure hunting stages. Jeez, it was so bad.
But then some of the music from those games...
https://www.youtube.com/watch?v=A5VBjq0oPZMI rented that and some harry potter game around the same time. Running around on treetops and finding the weird metal sonic that looked like shadow in eggman's secret base... And then exploring Hogwarts. God, that game was probably garbage, but thinking about it makes me feel all warm and fuzzy.
They need to make Encarta Mindmaze: Hogwarts edition.
