Armitage III, Cyber City Oedo 808 Recommendations
Two of the better classic cyberpunk OVA's that I've seen. Simply put if you like old, gritty, cyberpunk with adult themes, great action, etc, you'll enjoy both.
Both anime belong to the Cyberpunk genre. Both have similar settings and made in the same stylistic and format. If you liked the first you will definitely like the second.
But, if you haven't seen neither of this and a fan of the Cyberpunk genre - then check out both.
