ACEN is my local con. The only major issue I have with it is the lack in quantity & quality of Japanese guests. Not enough different directors, voice actors, artists & too many fashion guests & DJ's. Their guest relations doesn't seem to have the pull/connections compared to other major cons. It's like the con should easily sell itself to guests with Chicago steps away, but maybe not with all the crime news.
I haven't been to Otakon in a few year & am only wanting to attend this year to see how the new location turns out. Hopefully they'll have a good JP guest lineup as it's my main reason for attending these con's.
