i'm of the opinion that there's really no reason to play sonic adventure 2 yourself when you could watch a let's play or something, unless you want to do chao garden which you should probably just download a complete savefile or something
it's got
- a stuffty camera
- clunky controls for shooting levels
- a somewhat annoying way to pad game time by having 4 extra missions for each level where 2 of the 4 goals are played basically the same
- treasure hunting levels that take too long because they removed the feature from the first sonic adventure where you could find emeralds out of order
- less level variety than the first sonic adventure because sonic/shadow are the same, tails/eggman are the same, and knuckles/rouge are the same. they could've tried to at least differentiate them somehow, or at the very least not put tails in a dumb clunky walker
- mad space
- kart racing. seriously, the kart levels handle like ass and why would you ever play them
- omochao
- shadow is actually alright but then they brought him back retroactively making him a bad character
- jiggle physics on rouge's ears and boobs instead of like literally anything else they could have improved on with the time spent programming that
- that loving cutscene where sonic jumpkicks the boss and shouts TERIAAAAA like what the forget that is the most bullstuff reason to make you fight that boss on dark story instead of just making another boss
- (beats up eggman) "this time i'll let you go."
- the biolizard literally has the space colony ark shoved up its ass. what the forget
- the text is in comic sans
- not much actual adventuring
if my negativity upsets you, here are some positive things about sonic adventure 2
- the chao garden. those little asslings are so cute
- doesn't have big the cat as a playable character
- get your paws on a mess of rings for an extra lives
- yoshi yooooosh
