Mid in a game form, which really stings because it had a lot of potential. I should probably beat it again because I was so completely drained of the story by the time I got to case 4 and I did not care about the characters or plot in the slightest even though it gives so much insight to our little Edgey boy.
Jury's out on this one. Mobile port is fine, though after playing AAI2 I think playing it on the DS is more fun.
TLDR, read a summary and go play AAI2 (the best game in the series imo). The story of this game doesn't impact the second one anyway.
