Sure, I found the ending nicely satisfying. Still, from the scans that get posted here now and then, I'd love to have more Kaiji. There's the ugly girlfriend, the FOOTJUICE drinker creepy guy, Kaiji - thug costume, etc.
Much better than another season of only Washizu Mahjong for Akagi.
Once the ending for akagi is written, They should release 4 or 5 OVAs to finish up the eleven-year namek.
