Xexyz – Action (NES)
Hudson Soft

Although cursed with a name that makes no sense and is difficult (if it’s even possible) to pronounce, Xexyz is among the more underappreciated games out there.

Jumping Flash! 2 – Action (PSX)
Sony CEI

As a PSX game, JF! 2 may seem relatively short and overly easy. If you try it out, though, you might find a rewarding experience that is, yes, sadly far too short.

axanadu – Adventure/RPG (NES)
Hudson Soft / Falcom

If you’re thinking about playing an action RPG for NES, you’ve basically got two choices: Crystalis and Faxanadu. Faxanadu is evidently an offshoot from the Dragon Slayer series (a sequel to Xanadu), which Legacy of the Wizard is also from.

Deja Vu – Adventure / Mystery (NES/GBC)
Kemco / Icom Simulations

Honestly, I have been pressured into including this one by multiple people – I am not terribly fond of the mystery / adventure genres myself, but I have to admit that this game is very well done for what it is intended to be, and as a current translator of a game that is similar (if much more forgiving), this game offers more open-endedness.

Aerobiz / Aerobiz: Supersonic – Simulation/Strategy (SNES/GEN)
Koei

The SNES era was one of great experimentation for Koei. One of these experiments took the form of an airline business simulator – similar, I’d imagine, to what an Airline Tycoon game would be like (apparently one’s out, but I haven’t played it, nor do I plan to). You select a city and start out with an amount of money based on the starting city, and you buy airplanes and open routes between major world cities.
