Have been thinking would it be interesting to turn StarTropics into an RPG with that grid based movement and maybe a bit Zeldaish <img src="smileys/smiley1.gif" border="0" align="middle">
Also for some reason I always liked how Nox looked. That and tactical turn based combat, partly randomly generated world and party based RPG. Just a bit afraid that isometric character design with different items and all that.
My current main project is somewhat Doom inspired.
Also been working NES styled game prototype. TEST LEVEL
I also made one NES Castevania clone in the past I could maybe redo on C2.
Also found this hqx video setting on Nestopia yesterday

At least I find it rather interesting what it does.
Edit: Oh! And X-com the original from 1994. Xenonauts is the best remake so far.
