Here's some interface concepts....
Shadowrun SNES conversation chooser with keywords.
SCUMM command structure parser for Maniac Mansion.
I'm a big fan of Shadowrun on SNES. It was designed nearly like a PC game but on Super Nintendo.
The best part was speaking to NPCs you learn various code words. This was kinda more intuitive than the scheme used in BioWare's RPGs in the future.
Maniac Mansion I wasn't so good at compared to Shadowgate on NES. It had an inclusive interface using point and click. Another inspiration is Shenmue. But anyway, in the PnC mode you tell your character how to interact with the world around them. I won't stick with PnC for movement relying on the PC to walk to a place they are told to walk to because I hate that. I would have arrow keys or UO style movement using the mouse.
