(Dreamcast) Sonic Adventure 1 vs Sonic Adventure 2: are both worth a buy?

[Louie]

Wow, you guys actually answered. I´m impressed! Even Rol! :p

What I heard, though, is that the first game didn´t age all too well that´s why I´m not sure.

Oh and Rol, those "Viechers" are really cute! If they were in the new Sonic game I´d definitely buy it.
