I can think of one. It’s called Odium. (Known outside North America as Gorky 17). It’s also being re-released (By Topware, makers of it and Septerra Core) in its Best of Games: Role Playing. (Which I curse Futureshop and Best buy for never having despite having strategy and action available.)
Can anybody think of any others?
PS: I plan to make an Odium shrine once I finish my Heroes (PC/Mac and Gameboy) Shrine.
Black Onyx (or maybe they called the NES port Super Black Onyx?)
Famicom Jump 1, 2
Goemon Gaiden 1, 2
Hokuto no Ken 3, 4 (and 5 for SNES)
Hoshi wo Miru hito (working on a translation of this, planning to call it Stargazers)
Shin Satomi Hakkenden (a different game than Satomi Hakkenden, kinda resembles Bloody Warriors)
Mirai Shinwa Jarvas
Momotaro Densetsu (you already have Gaiden listed, which is a seperate game)
I initially though Dream Master, but I think that’s more on the puzzle genre.
Galaxy Oddyssey (combines Action-RPG planet exploration with a space shmup)
3x3 Eyes - Seima Korinden (aka 3x3 Eyes - Advent of the Divine Demon)
Maka Maka (or Maka-Maka)
Rage of Mages I&II for the PC. Fun games, both of them. edit: Also Deus Ex 2
How rpg-ish is Gorky? I had the impression it was in the vein of Incubation (squad where you can buy wepons/some equipment and hp can raise but is rather a strategy game). Regarding this best-of series Septerra Core was good if a bit obnoxious sometimes and Jack Orlando is a good noir adventure.
Gorky/Odium is more in the vein of FF tactics or Kartia, but it more closely resembles Vandal Hearts in the way it plays. Your characters level up, as do their skills with various weapons as they use them more. For guns it can be a bit more difficult to do so due to limited ammo, so levelling your melee weapons is crucial. Also, with each level your characters get a raise in HP and a choice of stat to level up as well. It’s a difficult game though, you need to keep every character alive.
